• maven集成SSM项目，Tomcat部署运行——SSM整合框架搭建（二）

    系列一jetty试运行的maven框架成功后，我决定先从熟悉的Tomcat运行入手

    第一步：添加相关依赖包

    各种包，分为为：springDI依赖包（最基础的必备包），AOP相关依赖，springMVC依赖包，servlet及jsp相关依赖，数据库库依赖包，mybatis及Mybatis-spring依赖包等，上代码pom.xml

181 </build>
182 </project>

     第二步，配置几个基础文件。应该从web.xml入手。这个是整个web程序的入口，相当于java的main函数，我在实际编码时并没有按照这个顺序，这里为了逻辑清楚，能够串联起来，我还是从这里说起，上代码；并将进行相应说明：

    1、配置web.xml

     1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
 3 <display-name>OrdersForGoods</display-name>
 4 
 5 <display-name>Archetype Created Web Application</display-name>
 6 <!-- 配置监听器加载上下文参数spring的配置文件 ,这个的作用是当tomcat启动程序时，首先会监听，加载相应的配置，
    　　好比是application读取文件流，构建一个bean工厂，用来为依赖注入DI做准备    --> 7 <context-param>
 8 <param-name>contextConfigLocation</param-name>
 9 <param-value>classpath:applicationContext-mybatis.xml</param-value>
10 </context-param>
11 <listener>
12 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
13 </listener>
14 <!-- 配置springmvc的servlet ，前端控制器作用就不说了，大家都明白-->
15 <servlet>
16 <servlet-name>springmvc</servlet-name> 注意：这里的的名字一定要和springMVC的配置文件XXX-servlet.xml中的XXX名字完全相等，否则报错
17 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
18 <init-param>
19 <param-name>contextConfigLocation</param-name>
20 <param-value>classpath:springmvc-servlet.xml</param-value>
21 </init-param>
22 <load-on-startup>1</load-on-startup>
23 </servlet>
24 <servlet-mapping>
25 <servlet-name>springmvc</servlet-name>
26 <url-pattern>/</url-pattern><!--这里用/是根目录的意思，之前我用/*是有问题的，这两者还是有区别的，大家自行文度娘-->
27 </servlet-mapping>
28 <!-- 配置过滤器 设置编码格式-->
29 <filter>
30 <filter-name>encoding</filter-name>
31 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
32 <init-param>
33 <param-name>encoding</param-name>
34 <param-value>utf-8</param-value>
35 </init-param>
36 </filter>
37 <filter-mapping>
38 <filter-name>encoding</filter-name>
39 <url-pattern>/*</url-pattern>
40 </filter-mapping>
41 <!-- 配置log4j日志的监听 容器启动就加载，同加载applicationContext.xml类似-->
42 <context-param>
43 <param-name>log4j</param-name>
44 <param-value>classpath:log4j.properties</param-value>
45 </context-param>
46 <listener>
47 <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
48 </listener>
49 </web-app>

    2、applicationContext.xml

     1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3   xmlns="http://www.springframework.org/schema/beans" 
 4   xmlns:aop="http://www.springframework.org/schema/aop"

16      http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
17      http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.3.xsd"
18      >
19      <!-- 加载jdbc属性文件 -->
20      <context:property-placeholder location="classpath:jdbc.properties"/>
21      <!-- 配置数据源 -->
22      <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" scope="singleton">
23          <property name="driverClassName" value="${jdbc.driver}"/>
24          <property name="url" value="${jdbc.url}"/>
25         <property name="username" value="${jdbc.username}"/>
26          <property name="password" value="${jdbc.password}"/>    
27      </bean>
28      <!-- 让事务注解生效 -->
29      <tx:annotation-driven/>
30      <!--配置事务 -->
31      <bean id="transaction" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
32      <property name="dataSource" ref="dataSource"/>
33      </bean>
34      <!-- 配置mybatis的sqlSessionFactory -->
35      <bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean">
36      <property name="dataSource" ref="dataSource"/>
37      <property name="configLocation" value="classpath:mybatis-config.xml"/>
38      </bean>
39      <!-- mapper 接口所在包名，spring自动查找下面mapper.xml并生产相应实例，让接口和xml相关联 -->
40      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
41      <property name="basePackage" value="com.yusys.dao"/>
42      </bean>
43      
44 </beans>

    3、springmvc-servlet.xml

     1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4     xmlns:p="http://www.springframework.org/schema/p"
 5     xmlns:context="http://www.springframework.org/schema/context"
 6     xmlns:mvc="http://www.springframework.org/schema/mvc"
 7     xsi:schemaLocation="
 8         http://www.springframework.org/schema/beans
 9         http://www.springframework.org/schema/beans/spring-beans.xsd
10         http://www.springframework.org/schema/context
11         http://www.springframework.org/schema/context/spring-context.xsd
12         http://www.springframework.org/schema/mvc
13         http://www.springframework.org/schema/mvc/spring-mvc.xsd">
14         <!-- 使项目所有注解生效 -->
15         <context:component-scan base-package="com.yusys"/>
16         <!-- 配置视图解析器 -->
17         <bean id="" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
18             <property name="prefix" value="/WEB-INF/jsp/"/>
19             <property name="suffix" value=".jsp"/>
20         </bean>
21         
22         
23         
24         </beans>

    4、mybatis-config.xml

    　　这个文件配置很少，主要是因为在SSM整合中，实际上主要是整合了mybatis，之前由mybatis进行配置的与数据库的联系全交给了spring去做，如数据源、连接池、事务等等。这些交给spring以后，当程序需要的时候，就会依赖注入的方式提供给程序用。springmvc主要作用可以先简单理解为调配调用，视图解析。

     1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE configuration
 3   PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
 4   "http://mybatis.org/dtd/mybatis-3-config.dtd">
 5   <configuration>
 6     <settings>
 7           <setting name="lazyLoadingEnabled" value="true"/>
 8       </settings>
 9       <typeAliases>
10           <package name="com.yusys.entity"/>
11       </typeAliases>
12   </configuration>

    基础的配置文件就是这些，至于mapper.xml，属于dao层的内容，我倾向于将它理解为java代码的另一种特殊存在形式，放在后文进行说明

    第三步、就是编写代码了（这里只是为了演示说明这个过程，就放一个相关的entity、dao、service、controller，其他的有兴趣的自己添加补充）。

    1、entity实体类

     1 package com.yusys.entity;
 2 
 3 import java.util.Date;
 4 
 5 public class NewsDetail {
 6 
 7     private int id;
 8     private String title;
 9     private String summary;
10     private String author;
11     private Date createdate;
12     public int getId() {
13         return id;
14     }
15     public void setId(int id) {
16         this.id = id;
17     }
18     public String getTitle() {
19         return title;
20     }
21     public void setTitle(String title) {
22         this.title = title;
23     }
24     public String getSummary() {
25         return summary;
26     }
27     public void setSummary(String summary) {
28         this.summary = summary;
29     }
30     public String getAuthor() {
31         return author;
32     }
33     public void setAuthor(String author) {
34         this.author = author;
35     }
36     public Date getCreatedate() {
37         return createdate;
38     }
39     public void setCreatedate(Date createdate) {
40         this.createdate = createdate;
41     }
42     
43 }

    2、dao层

     1 package com.yusys.dao;
 2 
 3 import java.util.List;
 4 
 5 import com.yusys.entity.NewsDetail;
 6 
 7 public interface NewsDetailMapper {
 8     
 9     public List<NewsDetail> getAll();
10     
11     public List<NewsDetail> getNewsDetailByTitle();
12 }
     1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
 3   "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
 4   <mapper namespace="com.yusys.dao.NewsDetailMapper">
 5   <select id="getAll" resultType="NewsDetail">
 6       select * from news_detail
 7   </select>
 8   <select id="getNewsDetailByTitle" parameterType="NewsDetail" resultType="NewsDetail">
 9       select * from news_detail where title like concat('%',#{title},'%') 
10   </select>
11   </mapper>

    3、service层

     1 package com.yusys.service;
 2 
 3 import java.util.List;
 4 
 5 import com.yusys.entity.NewsDetail;
 6 
 7 public interface NewsDetailService {
 8 
 9     public abstract List<NewsDetail> getAll();
10 
11     public abstract List<NewsDetail> getNewsDetailByTitle();
12 
13 }
    NewsDetailService
     1 package com.yusys.service;
 2 
 3 import java.util.List;
 4 
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.stereotype.Service;
 7 
 8 import com.yusys.dao.NewsDetailMapper;
 9 import com.yusys.entity.NewsDetail;
10 @Service
11 public class NewsDetailServiceImpl implements NewsDetailService {
12     @Autowired
13     NewsDetailMapper newsDetailMpper;
14     
15     /* (non-Javadoc)
16      * @see com.yusys.service.NewsDetailService#getAll()
17      */
18     @Override
19     public List<NewsDetail> getAll(){
20         return newsDetailMpper.getAll();
21     }
22     
23     /* (non-Javadoc)
24      * @see com.yusys.service.NewsDetailService#getNewsDetailByTitle()
25      */
26     @Override
27     public List<NewsDetail> getNewsDetailByTitle(){
28         return newsDetailMpper.getNewsDetailByTitle();
29     }
30 }

    4、controller层

     1 package com.yusys.controller;
 2 
 3 import java.util.List;
 4 
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.stereotype.Controller;
 7 import org.springframework.ui.Model;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 
10 import com.yusys.entity.NewsDetail;
11 import com.yusys.service.NewsDetailService;
12 @Controller
13 public class NewsDetailController {
14     @Autowired
15     NewsDetailService newsDetailService;
16     
17     @RequestMapping(value="/newsDetailList")
18     public String getAllDetail(Model model){
19         List<NewsDetail> list=newsDetailService.getAll();
20         model.addAttribute("list", list);
21         return "newsDetail";
22     }
23 }

    第四步、创建newsDetail.jsp进行显示。

    第五步、部署tomcat进行运行

    1、

    2、

    3、点击下一步后添加项目后finish

    4、tomcat未启动是双击

    5、进入Overview界面，选择以下配置，关闭该界面

    6、启动tomcat，运行程序，注掉controller中的方法调用，让其直接转到jsp页面，效果显现，一切OK，但是放开里面的方法，出现了问题，mysql的jar和tomcat的jar冲突的问题，具体问题及其他见相应的博文——maven集成SSM项目，Tomcat部署运行——SSM整合框架搭建（二）之问题
