• spring多模块项目手动整合


    一、分别创建parent entity dao service controller web等模块项目,如图:

      

    二、parent项目添加依赖

    <!-- 集中定义依赖版本号 -->

                </plugins>
            </pluginManagement>
        </build>

    三、Spring整合SpringMVC

    3.1 在web项目,添加依赖

    <dependencies>
            <dependency>
                <groupId>com.stu</groupId>
                <artifactId>parent</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
            <dependency>
                <groupId>com.stu</groupId>
                <artifactId>service</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
            <!-- JSP相关 -->
            <dependency>
                <groupId>jstl</groupId>
                <artifactId>jstl</artifactId>
            </dependency>
            <dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>servlet-api</artifactId>
                <scope>provided</scope>
            </dependency>
            <dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>jsp-api</artifactId>
                <scope>provided</scope>
            </dependency>
            <!-- 文件上传组件 -->
            <dependency>
                <groupId>commons-fileupload</groupId>
                <artifactId>commons-fileupload</artifactId>
            </dependency>
            <!-- springwebmvc -->
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-webmvc</artifactId>
            </dependency>
            <dependency>
                <groupId>com.stu</groupId>
                <artifactId>entity</artifactId>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-annotations</artifactId>
                <version>2.5.0</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-core</artifactId>
                <version>2.5.0</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.jr</groupId>
                <artifactId>jackson-jr-all</artifactId>
                <version>2.5.0</version>
            </dependency>
        </dependencies>

    3.2 添加springmvc的配置文件,srcmain esourcesspringspringmvc.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:p="http://www.springframework.org/schema/p"
           xmlns:context="http://www.springframework.org/schema/context"
           xmlns:mvc="http://www.springframework.org/schema/mvc"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
        <!-- springmvc 扫包范围 -->
        <context:component-scan base-package="com.stu.controller"/>
        <!-- 开启springmvc注解 -->
        <mvc:annotation-driven/>
        <!-- 视图跳转类型 -->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/jsp/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
    </beans>

    如果xml出现 URI is not registered,点击菜单栏“File”→“Settings”→“Languages&Frameworks”→如图点击加号,会弹出来一个内容框,将上图中报红色的内容复制,然后apply

    3.3 在web.xml加载springmvc配置

    <!-- 解决post乱码 -->
        <filter>
            <filter-name>CharacterEncodingFilter</filter-name>
            <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
            <init-param>
                <param-name>encoding</param-name>
                <param-value>UTF-8</param-value>
            </init-param>
            <!-- <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value>
                </init-param> -->
        </filter>
        <filter-mapping>
            <filter-name>CharacterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>
        <!-- springmvc的前端控制器 -->
        <servlet>
            <servlet-name>stu-web</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <!-- contextConfigLocation不是必须的, 如果不配置contextConfigLocation, springmvc的配置文件默认在:WEB-INF/servlet的name+"-servlet.xml" -->
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:spring/springmvc.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>stu-web</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>

    3.4 测试SpringMVC搭建情况

    @Controller
    public class TestController {
        // 测试页面
        private static final String TEST = "test";
        @RequestMapping("/hello")
        public String hello(){
            System.out.println("hello******************************");
            return TEST;
        }
    }

    在WEB-INF/jsp/test.jsp地址下创建jsp页面

    四、Spring整合MyBatis

    4.1 表结构说明

    --视频类型表
    CREATE TABLE `video_type` (
      `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键(自增长)',
      `type_name` varchar(30) DEFAULT NULL COMMENT '视频类型',
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
    --视频详情表
    CREATE TABLE `video_info` (
      `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键(自增长)',

    jdbc.userName=root
    jdbc.passWord=
    jdbc.initialSize=0
    jdbc.maxActive=20
    jdbc.maxIdle=20
    jdbc.minIdle=1
    jdbc.maxWait=10000

    4.5 添加 spring/applicationContext-service.xml

            <property name="dataSource" ref="dataSource" />
        </bean>
    </beans>

    4.7 添加 spring/applicationContext-trans.xml (事物管理器、AOP切面设置)

    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
           xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
        <!-- 事务管理器 -->
        <bean id="transactionManager"
              class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <!-- 数据源 -->
            <property name="dataSource" ref="dataSource" />
        </bean>
        <!-- 通知 -->
        <tx:advice id="txAdvice" transaction-manager="transactionManager">
            <tx:attributes>
                <!-- 传播行为 -->
                <tx:method name="save*" propagation="REQUIRED" />
                <tx:method name="insert*" propagation="REQUIRED" />
                <tx:method name="add*" propagation="REQUIRED" />
                <tx:method name="create*" propagation="REQUIRED" />
                <tx:method name="delete*" propagation="REQUIRED" />
                <tx:method name="update*" propagation="REQUIRED" />
                <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
                <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
                <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
            </tx:attributes>
        </tx:advice>
        <!-- 切面 -->
        <aop:config>
            <aop:advisor advice-ref="txAdvice"
                         pointcut="execution(* com.stu.service.*.*(..))" />
        </aop:config>
    </beans>

    4.8 使用 generator 生成数据ORM映射文件,生成表结构对应的 entity实体类、mapper类、mapping.xml文件

    4.9 web.xml 配置加载sping文件

    <!-- 加载spring容器 -->
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/applicationContext-*.xml</param-value>
        </context-param>
        <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

    4.10 测试MyBatis是否整合成功

    @Controller
    public class VideoTypeController {
        private Logger logger = Logger.getLogger(VideoTypeController.class);
        @Autowired
        private VideoTypeService videoTypeService;
        @ResponseBody
        @RequestMapping("/getVideoTypeList")
        public List<VideoType> getVideoTypeList(){
            List<VideoType> videoTypeList = videoTypeService.getVideoTypeList(null);
            for (VideoType vt : videoTypeList) {
                logger.error(vt.toString());
            }
            return videoTypeList;
        }
    }

    五、Spring整合log4j

      在 resource 添加 properties/log4j.properties

    ### set log levels ###
    log4j.rootLogger =INFO,DEBUG,stdout,R
    
    log4j.appender.stdout = org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.Target = System.out
    log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern = [%-5p]%d{yyyy-MM-ddHH:mm:ss,SSS}method:%l%n%m%n
    
    log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
    log4j.appender.D.File = E://logs/log.log
    log4j.appender.D.Append = true
    log4j.appender.D.Threshold = DEBUG
    log4j.appender.D.layout = org.apache.log4j.PatternLayout
    log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-ddHH:mm:ss}[%t:%r]-[%p]%m%n
    
    log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
    log4j.appender.E.File =E://logs/error.log
    log4j.appender.E.Append = true
    log4j.appender.E.Threshold = ERROR
    log4j.appender.E.layout = org.apache.log4j.PatternLayout
    log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-ddHH:mm:ss}[%t:%r]-[%p]%m%n

      在web.xml配置加载log4j

    <!--设置log4j的配置文件位置 -->
        <context-param>
            <param-name>log4jConfigLocation</param-name>
            <param-value>/WEB-INF/classes/properties/log4j.properties</param-value>
        </context-param>
        <!--使用监听加载log4j的配置文件 -->
        <listener>
            <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
        </listener>

      使用API: private static Logger log = Logger.getLogger(TestController.class);
