  • spring mvc4.1.6 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明

    一、准备工作

    开始之前,先参考上一篇:

    struts2.3.24 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明

    struts2.3.24 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明

    struts2.3.24 + spring4.1.6 + hibernate4.3.11 + mysql5.5.25 开发环境搭建及相关说明

    思路都是一样的,只不过把struts2替换成了spring mvc

    二、不同的地方

    工程目录及jar包:

    action包改成controller;

    删除struts2 jar包,添加spring mvc包(已有的话,不需添加);

       

    web.xml配置:

    跟之前不同的地方是把struts2的过滤器替换成了一个servlet,主要目的是路由url,交给spring mvc处理;

    <?xml version="1.0" encoding="UTF-8"?>
    <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">
      <display-name>SSH</display-name>
    
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
    
      <welcome-file-list>
          <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
    
    
      <servlet>
          <servlet-name>springmvc</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath:springmvc-servlet.xml</param-value>
          </init-param>
          <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
          <servlet-name>springmvc</servlet-name>
          <url-pattern>*.do</url-pattern>
      </servlet-mapping>
    
    
    </web-app>

    applicationContext.xml配置:

    不同的地方主要是配置自动扫描的时候,要排除@Controller组件,这些bean是由spring mvc 去生成的;

    其它配置跟前一篇一样;

    <?xml version="1.0" encoding="UTF-8"?>

            </aop:aspect>
        </aop:config>
        
    
    
     </beans>

    springmvc-servlet.xml配置:

    配置自动扫描ssh.controller包下的@Controller,这里要恢复applicationContext.xml中配置的exclude-filter;

    配置视图解析器,有很多解析器,这里以InternalResourceViewResolver为例;

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xmlns:p="http://www.springframework.org/schema/p"
        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-4.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-4.1.xsd
            http://www.springframework.org/schema/mvc
            http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
            http://www.springframework.org/schema/tx
            http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
            ">
            
        <!-- 启动自动扫描该包下所有的Bean(例如@Controller) -->
        <context:component-scan base-package="ssh.controller" >
            <!-- 恢复父容器设置的 exclude-filter,注意包扫描路径ssh.controller-->
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />  
        </context:component-scan>
        
        <!-- 定义视图解析器 -->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix">
                <value>/WEB-INF/jsp/</value>
            </property>
            <property name="suffix">
                <value>.jsp</value>
            </property>
        </bean>
        
    </beans>

    编写controller:

    由于使用spring mvc替换struts2,也就没有了action包了,删除,并新建controller包,在包下新建UserController类;

    @RequestMapping:映射url;

    @ResponseBody:内容直接作为body返回;

    UserController.java

    package ssh.controller;
    
    import java.io.PrintWriter;
    import java.util.List;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import org.apache.log4j.Logger;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import ssh.aop.AopTest;
    import ssh.model.User;
    import ssh.service.UserService;
    
    import com.google.gson.Gson;
    
    @Controller
    @RequestMapping("/user")
    public class UserController {
        Logger logger = Logger.getLogger(UserController.class);
        @Resource
        private UserService userService;
        @Resource
        private AopTest aopTest;
        
        @RequestMapping(value="/addUser")
        @ResponseBody
        public void addUser(HttpServletRequest request, HttpServletResponse response){
            PrintWriter out = null;
            try{
                response.setContentType("text/html;charset=UTF-8");
                String account = request.getParameter("account");
                String name = request.getParameter("name");
                String address = request.getParameter("address"); 
                User user = new User();
                user.setAccount(account);
                user.setAddress(address);
                user.setName(name);
                userService.add(user);
                out = response.getWriter();
                out.write(new Gson().toJson("success"));
            }catch(Exception e){
                e.printStackTrace();
                logger.error(e.getMessage());
                if(out != null)
                    out.write(new Gson().toJson("fail"));
            }finally{
                out.flush();
                out.close();
            }
            
        }
        
        @RequestMapping(value="/queryUser")
        @ResponseBody
        public void queryAllUser(HttpServletRequest request, HttpServletResponse response){
            PrintWriter out = null;
            
            aopTest.test1();
            aopTest.test2();
            
            try {
    
                response.setContentType("text/html;charset=UTF-8");
        
                Gson gson = new Gson();
                List<User> userList= userService.queryAllUser();
                String gsonStr = gson.toJson(userList);
                
                out = response.getWriter();
                out.write(gsonStr);
            } catch (Exception e) {
                e.printStackTrace();
                logger.error(e.getMessage());
                if(out != null)
                    out.write(new Gson().toJson("fail"));
            }finally{
                out.flush();
                out.close();
            }
        }
    }

    三、运行程序

    运行程序,添加用户、查询用户功能正常;

    另外二级缓存也正常工作,第二次查询已经没有操作数据库了;
