【spring配置】——springMVC配置

Spring所有的配置都可以分为XML和Annotation两种。

首先需要导入Spring的jar包，然后在项目的web.xml中配置dispatchServlet。

<!-- SpringMVC拦截器 -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/application-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

xml配置方式：

1.使用BeanNameUrlHandlerMapping/SimpleControllerHandlerAdapter

使用SimpleControllerHandlerAdapter需要Controller实现Controller接口：

package com.xy.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

/**
* SpringMVC xml配置方式Controller
* 必须实现Controller接口
* @author javaw
*
*/
public class TestController implements Controller {

public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
return new ModelAndView("test").addObject("id", "123");
}

}

xml：

<property name="prefix" value="/WEB-INF/"/>
<property name="suffix" value=".jsp"/>
</bean>

</beans>

2.使用SimpleUrlHandlerMapping/HttpRequestHandlerAdapter

使用HttpRequestHandlerAdapter需要实现HttpRequestHandler接口，且request.getRequestDispatcher("")的地址需要指定全路径;

package com.xy.controller;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.HttpRequestHandler;

public class TestController1 implements HttpRequestHandler{

public void handleRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.getRequestDispatcher("/WEB-INF/test.jsp").forward(request, response);
}
}

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"

Annotation配置方式

配置文件：

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

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping(value="/test")
public class TestController {

@RequestMapping(value="/toTestPage.do")
public ModelAndView toTestPage(HttpServletRequest request,HttpServletResponse response){
