SSM框架的簡單整合2-Spring+SpringMVC

需求：在Spring的基礎上整合SpringMVC

IDE工具：Eclipse

搭建環境：jdk1.8 tomcat8.5

目前的項目結構如下：

說明：在集成SpringMVC的時候，我將項目名稱改爲SSMTest2。

開整。

1.編寫SpringMVC的配置文件

1.1 配置文件內容如下：

<?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"
   xmlns:mvc="http://www.springframework.org/schema/mvc"
   xmlns:aop="http://www.springframework.org/schema/aop"
   xsi:schemaLocation="http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">

<context:component-scan base-package="com.yzpt">
       <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
   </context:component-scan>

<bean id="internalResourceViewResolver"
       class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name="prefix" value="/WEB-INF/jsp/"></property>
       <property name="suffix" value=".jsp"></property>
   </bean>

<mvc:default-servlet-handler />

<mvc:annotation-driven />

<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
</beans>

1.2 在配置中配置了aspectj，因此需要添加aspectj依賴，如下：

<dependency>
           <groupId>org.aspectj</groupId>
           <artifactId>aspectjrt</artifactId>
           <version>1.9.2</version>
       </dependency>

2. 在web.xml中指定SpringMVC的加載路徑，並且配置字符編碼過濾器，如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://xmlns.jcp.org/xml/ns/javaee"
   xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
   version="3.1">
   <display-name>SSMTest2</display-name>
   <welcome-file-list>
       <welcome-file>index.jsp</welcome-file>
   </welcome-file-list>
   
   <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>

   
   <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.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
       <servlet-name>springMVC</servlet-name>
       <url-pattern>/</url-pattern>
   </servlet-mapping>

   
   <filter>
       <filter-name>encodingFilter</filter-name>
       <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
       <async-supported>true</async-supported>
       <init-param>
           <param-name>encoding</param-name>
           <param-value>UTF-8</param-value>
       </init-param>
   </filter>
   <filter-mapping>
       <filter-name>encodingFilter</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>
</web-app>

3. 爲了方便測試，這裏添加了一個jsp頁面，如下圖：

test.jsp內容如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test</title>
</head>
<body>
<div>書的id：${book.bookId }</div>
<div>書的姓名：${book.bookName }</div>
<div>書的作者：${book.writer }</div>
<div>書的出版社：${book.publishingHouse }</div>
</body>
</html>

頁面上使用了EL表達式，因此需要引入2個jar包，一個是Servlet 2.5，一個是jstl 1.2，如下：

<dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>servlet-api</artifactId>
           <version>2.5</version>
           <scope>provided</scope>
       </dependency>

<dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>jstl</artifactId>
           <version>1.2</version>
       </dependency>

4. 編寫BookController類，內容如下：

package com.yzpt.web;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.yzpt.entity.Book;

@Controller
@RequestMapping
public class BookController {

   @RequestMapping(value ="/test" , produces = "application/json;charset=utf-8")
   @ResponseBody
   public String getResult() {
       return "Hello,EveryOne,I'm ZhaZhaHui!\n大家好，我是渣渣輝！";
   }

   @RequestMapping(value ="/Test")
   public String getTestInfo(HttpServletRequest request) {
       Book book = new Book();
       book.setBookId("10086");
       book.setWriter("YZP");
       book.setBookName("論客戶的重要性");
       book.setPublishingHouse("HaoYiTec");
       request.setAttribute("book",book);
       return "test";
   }
}

5. 編寫好控制器後，啓動項目，成功，如下：
