SpringMVC学习记录
1、HelloWorld
1、新建web工程，添加jar包
2、配置web.xml配置springmvc核心控制器(DispatcherServlet):作用是加载springmvc的配置文件,核心控制器自动加载默认位置配置文件，默认位置为web-inf下，默认名称为***-servlet.xml
span>app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >Archetype Created Web Application springMVC class>org.springframework.web.servlet.DispatcherServlet class>springMVC /
springMVC-servlet.xml
3、创建一个pojo
@Controller
public class Test {
@RequestMapping(value = "hello",method = RequestMethod.GET)//value设置请求路径，method用于约束请求类型
public String hello() {
System.out.println("111");
return "success";
}
}
4、编写jsp测试代码
Hello World!
测试springmvc
5、测试post请求
@RequestMapping(value = "hello",method = RequestMethod.POST)
public String hello1() {
System.out.println("POST");
return "success";
}
@RequestMapping解析：
占位符与占位符里值的获取示例（@pathvariable注解）:
//占位符
@RequestMapping(value = "/test/{id}/{name}")
public String hello2(@PathVariable("id") Integer id, @PathVariable("name") String name) {
System.out.println("id" + id + ",name:" + name);
return "success";
}
