通过该demo,可以 熟悉下 spring+cxf+maven+mybatis+mysql等常见后端技术整合
1. 在前面的 父工程 ws_parent 中 添加依赖
由于原来的项目是使用的cxf依赖,现在需要集成spring,mybatis,所以需要在父工程添加依赖,最新的父工程的pom文件如下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.lonely.webservice</groupId> <artifactId>ws_parent</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>pom</packaging> <properties> <spring-version>4.1.7.RELEASE</spring-version> <mybatis.version>3.4.1</mybatis.version> <mybatis.spring.version>1.3.0</mybatis.spring.version> <pagehelper.version>4.0.0</pagehelper.version> <mysql.version>5.1.32</mysql.version> <druid.version>1.0.9</druid.version> <jstl.version>1.2</jstl.version> <servlet-api.version>2.5</servlet-api.version> <jsp-api.version>2.0</jsp-api.version> <slf4j.api.version>1.7.10</slf4j.api.version> <logback.version>1.1.7</logback.version> <dbcp.version>1.4</dbcp.version> </properties> <!-- 配置依赖 --> <dependencyManagement> <dependencies> <!-- spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring-version}</version> </dependency> <!-- cxf依赖 --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-core</artifactId> <version>3.1.6</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>3.1.6</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http-jetty</artifactId> <version>3.1.6</version> </dependency> <!-- mybatis依赖 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${mybatis.spring.version}</version> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>${pagehelper.version}</version> </dependency> <!-- mysql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <!-- 连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>${druid.version}</version> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>${dbcp.version}</version> </dependency> <!-- JSP相关 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>${servlet-api.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-api.version}</version> <scope>provided</scope> </dependency> <!-- 日志处理 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.api.version}</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>${logback.version}</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>${logback.version}</version> </dependency> </dependencies> </dependencyManagement> <!-- 配置插件信息 --> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> <modules> <module>ws_server</module> <module>ws_client</module> <module>ws_ssm_server</module> </modules> </project>
2. 新建一个maven子工程 ws_ssm_server
2.1 新建一个子工程,打包方式为 war格式,因为spring的很多依赖有重复,经整理后 其pom文件如下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.lonely.webservice</groupId> <artifactId>ws_parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>ws_ssm_server</artifactId> <packaging>war</packaging> <dependencies> <!-- spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <!-- 添加 cxf 依赖 --> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-core</artifactId> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http-jetty</artifactId> </dependency> <!-- mybatis依赖 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> </dependency> <!-- mysql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- 连接池 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> </dependency> <!-- 日志处理 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> </dependency> </dependencies> </project>2.2 spring整合cxf
2.2.1 在web.xml中添加 cxf 拦截器处理器配置,以及 spring容器启动创建配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- 字符编码过滤器,必须放在过滤器的最上面 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>characterEncoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/application.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置cxf拦截器 --> <servlet> <servlet-name>cxfServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>cxfServlet</servlet-name> <url-pattern>/cxf/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>2.2.2 在resource目录下 创建文件夹 spring,在里面创建spring与cxf集成的配置文件 : spring-cxf.xml
这里注意要添加一个 jaxws的命名空间,以及引入两个 cxf中的 xml配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 定义服务提供者 --> <jaxws:endpoint implementor="#userService" address="/UserService" > <!-- 添加入 in 拦截器 --> <jaxws:inInterceptors> <bean class="com.lonely.interceptor.AuthInterceptor"></bean> <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean> </jaxws:inInterceptors> <!-- 添加 出 out 拦截器 --> <jaxws:outInterceptors> <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean> </jaxws:outInterceptors> </jaxws:endpoint> </beans>2.2.3 jaxws:endpoint 中的 implementor:对应的服务接口的实现类,而 address :对应发布的接口路径,注意在实际的接口实现类上 使用注解 @Component让spring 扫描发现管理,给个别名用于在了 implementor属性上
UserService
package com.lonely.service; import java.util.List; import java.util.Map; import javax.jws.WebService; import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter; import com.lonely.adapter.MapConvertAdapter; import com.lonely.model.Clazz; import com.lonely.model.User; @WebService public interface UserService { /** * 根据班级信息返回该班级的学生列表 * * @param clazz * @return */ List<User> findUsersByClass(Clazz clazz); /** * 查看所有班级信息以及班级下的所有学生 * * @return */ @XmlJavaTypeAdapter(value = MapConvertAdapter.class) Map<String, List<User>> findAll(); }UserServiceImpl
package com.lonely.service.impl; import java.util.HashMap; import java.util.List; import java.util.Map; import javax.jws.WebService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.lonely.dao.UserDao; import com.lonely.model.Clazz; import com.lonely.model.User; import com.lonely.service.UserService; @Component("userService") @WebService public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public List<User> findUsersByClass(Clazz clazz) { return this.userDao.findUsersByClass(clazz); } @Override public Map<String, List<User>> findAll() { List<Clazz> clazzList = this.userDao.findAll(); if (clazzList != null && clazzList.size() != 0) { Map<String, List<User>> map = new HashMap<>(); for (Clazz clazz : clazzList) { map.put(clazz.getClassName(), clazz.getUsers()); } return map; } return null; } }
2.3 spring整合mybatis
2.3.1 在spring目录下,添加 spring与mybatis集成的配置 : spring-datasource.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"> <!-- 配置数据源 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="username" value="${jdbc.jdbcUsername}"></property> <property name="password" value="${jdbc.jdbcPassword}"></property> <property name="url" value="${jdbc.jdbcUrl}"></property> <property name="driverClassName" value="${jdbc.driverClassName}"></property> </bean> <!-- 配置sqlsessionfactory --> <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置数据源 --> <property name="dataSource" ref="dataSource"></property> <!-- 配置mybatis配置 --> <property name="configuration"> <bean class="org.apache.ibatis.session.Configuration"> <!-- 开启驼峰命名法 --> <property name="mapUnderscoreToCamelCase" value="true"></property> <!-- 当检测出未知列(或未知属性)时,如何处理,默认情况下没有任何提示,这在测试的时候很不方便,不容易找到错误。 可选值: NONE : 不做任何处理 (默认值) WARNING : 警告日志形式的详细信息 FAILING : 映射失败,抛出异常和详细信息 --> <property name="autoMappingUnknownColumnBehavior" value="WARNING"></property> </bean> </property> <!-- 配置mapping扫描 --> <property name="mapperLocations" value="classpath:mapper/**/*.xml"></property> <!-- 配置别名包扫描 --> <property name="typeAliasesPackage" value="com.lonely.model"></property> <!-- 配置pagehelper 数据库方言 --> <property name="plugins"> <list> <bean class="com.github.pagehelper.PageHelper"> <property name="properties"> <value>dialect=mysql</value> </property> </bean> </list> </property> </bean> <!-- 配置 接口与 mapper的映射 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.lonely.dao"></property> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"></property> </bean> <!-- 配置事务 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 开启事务注解 --> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>2.3.2 在 basePackage 对应的路径下 编写 dao层的接口
package com.lonely.dao; import java.util.List; import com.lonely.model.Clazz; import com.lonely.model.User; public interface UserDao { List<User> findUsersByClass(Clazz clazz); List<Clazz> findAll(); }2.3.3 在 mapperLocations 对应的路径下 编写 mybatis的sql操作的xml文件,这里比如如下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.lonely.dao.UserDao"> <resultMap type="clazz" id="clazzMap"> <id property="classId" column="classId"/> <result property="className" column="className"/> <collection property="users" ofType="user"> <id column="id" property="id"/> <result property="userName" column="userName"/> <result property="classId" column="classId"/> </collection> </resultMap> <!-- 根据班级信息查询所有学生 --> <select id="findUsersByClass" parameterType="clazz" resultType="user"> SELECT * from user u where u.classId = #{classId} </select> <!-- 查询所有班级信息以及班级下的所有学生列表 --> <select id="findAll" resultMap="clazzMap"> SELECT * FROM clazz c JOIN USER u ON c.classId = u.classId </select> </mapper>2.3.4 在这里 使用了 mybatis的一对多,所以在 Clazz实体类上 多加了一个属性 List<User> users;
2.3.5 忘了 前面还需要一个 jdbc.properties
## jdbc环境配置 jdbc.driverClassName = com.mysql.jdbc.Driver jdbc.jdbcUrl = jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8&allowMultiQueries=true jdbc.jdbcUsername = root jdbc.jdbcPassword = xxx #jdbc.logAbandoned = false #jdbc.initialSize = 20 #jdbc.maxActive =1000 #jdbc.maxIdle=100 #jdbc.maxWait = 1000 #jdbc.minEvictableIdleTimeMillis = 300000 #jdbc.minIdle = 10 #jdbc.removeAbandoned = true #jdbc.removeAbandonedTimeout = 3000 #jdbc.timeBetweenEvictionRunsMillis = 10000 #jdbc.testOnBorrow = false #jdbc.testWhileIdle = true #jdbc.validSql = select now()
2.4 spring+cxf+mybatis
2.4.1 在spring目录下 创建一个spring的核心文件 application.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 引入配置文件 --> <context:property-placeholder file-encoding="UTF-8" location="classpath:properties/jdbc.properties"/> <!-- 包扫描 --> <context:component-scan base-package="com.lonely"></context:component-scan> <!-- spring与mybaties的整合 --> <import resource="spring-datasource.xml"/> <!-- spring与cxf的整合 --> <import resource="spring-cxf.xml"/> </beans>2.4.2 至此,spring+cxf+mybatis整合完毕,整个项目结构如下
