• SpringMVC初次尝试

    1.1、在pom.xml中添加依赖

    1. <dependency>
    2.       <groupId>org.springframeworkgroupId>
    3.       <artifactId>spring-contextartifactId>
    4.       <version>4.2.6.RELEASEversion>
    5.     dependency>
    6.     <dependency>
    7.       <groupId>org.springframeworkgroupId>
    8.       <artifactId>spring-webartifactId>
    9.       <version>4.2.6.RELEASEversion>
    10.     dependency>
    11.     <dependency>
    12.       <groupId>org.springframeworkgroupId>
    13.       <artifactId>spring-webmvcartifactId>
    14.       <version>4.2.6.RELEASEversion>
    15.     dependency>

    1.1、添加Spring的配置文件beans.xml

    1. "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:context="http://www.springframework.org/schema/context"
    5.        xmlns:mvc="http://www.springframework.org/schema/mvc"
    6.        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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    7.  
    8.     
    9.     <mvc:annotation-driven/>
    10.     
    11.     <context:component-scan base-package="demo.controller"/>
    12.  
    13.     
    14.     <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    15.         
    16.         
    17.         <property name="prefix" value="/views/"/>
    18.         
    19.         <property name="suffix" value=".html"/>
    20.     bean>
    21. beans>

    1.3、在web.xml中配置SpringMVC

    1. web-app PUBLIC
    2.  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    3.  "http://java.sun.com/dtd/web-app_2_3.dtd" >
    4.  
    5. <web-app>
    6.   
    7.   <servlet>
    8.     <servlet-name>springMVCservlet-name>
    9.     <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
    10.     <init-param>
    11.       
    12.       <param-name>contextConfigLocationparam-name>
    13.       <param-value>classpath:beans.xmlparam-value>
    14.     init-param>
    15.     <load-on-startup>1load-on-startup>
    16.   servlet>
    17.   <servlet-mapping>
    18.     <servlet-name>springMVCservlet-name>
    19.     <url-pattern>/url-pattern>
    20.   servlet-mapping>
    21. web-app>

    1.4、在web.xml中配置允许访问静态文件

    2.   <servlet-mapping>
    3.     <servlet-name >default
    4.     <url-pattern >*.jsurl-pattern>
    5.   
    6.   <servlet-mapping >
    7.     <servlet-name >default
    8.     <url-pattern >*.cssurl-pattern>
    9.   
    10.   <servlet-mapping >
    11.     <servlet-name >default
    12.     <url-pattern >*.htmlurl-pattern>
    13.   
    14.   <servlet-mapping >
    15.     <servlet-name >default
    16.     <url-pattern >*.gifurl-pattern>
    17.

    1.5、在webapp文件夹下添加demo01.html

    在\webapp\views\文件夹下创建demo01.html文件

    1. <body>
    2.     你好SpringMVC
    3. body>

    1.6、添加Controller

    1. package demo.controller;
    2.  
    3. import org.springframework.stereotype.Controller;
    4. import org.springframework.web.bind.annotation.RequestMapping;
    5.  
    6. @Controller
    7. public class DemoController {
    8.     @RequestMapping("/index")
    9.     public String index1(){
    10.         return "demo01";
    11.     }
    12. }

    1.7、浏览器访问测试

    在浏览器中访问controller，可以正常跳转到demo01.html

    二、添加JSON支持

    2.1、在beans.xml中添加JSON的消息转换器

    2.     <mvc:annotation-driven>
    3.         <mvc:message-converters register-defaults="true">
    4.             <bean class="org.springframework.http.converter.StringHttpMessageConverter">
    5.                 <constructor-arg value="UTF-8"/>
    6.             bean>
    7.             <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    8.                 <property name="objectMapper">
    9.                     <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
    10.                         <property name="failOnEmptyBeans" value="false"/>
    11.                     bean>
    12.                 property>
    13.             bean>
    14.         mvc:message-converters>
    15.     mvc:annotation-driven>

    2.2、添加User实体

    1. public class User {
    2.     private int id;
    3.     private String uname;
    4.   	//省略Getter和Setter
    5. }

    2.3、在Controller中测试

    1. package demo.controller;
    2.  
    3. import org.springframework.web.bind.annotation.RequestMapping;
    4. import org.springframework.web.bind.annotation.RestController;
    5.  
    6. @RestController
    7. public class TestController {
    8.  
    9.     @RequestMapping("/test2")
    10.     public User test2(){
    11.         User user = new User(1001, "张三");
    12.         return user;
    13.     }
    14. }

    2.4、在浏览器中进行测试

    浏览器中访问controller进行测试
