1.乱码的解决--通过过滤器来解决乱码：springmvc中提供CharacterEncodingFilter解决post乱码

 

<filter>
      <filter-name>CharacterEncodingFilter</filter-name>
      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
      <init-param>
          <param-name>encoding</param-name>
          <param-value>utf-8</param-value>
      </init-param>
  </filter>
  <filter-mapping>
      <filter-name>CharacterEncodingFilter</filter-name>
      <url-pattern>*.do</url-pattern>
  </filter-mapping>

 

如果是get方式乱码：1.修改tomcat的配置解决 2.自定义乱码解决的过滤器

2.restful风格的url

优点：轻量级，安全，效率高

//http://localhost:8888/springmvc_data/1/123/delete.do
    @RequestMapping("/{id}/{uid}/delete")
    public String hello(@PathVariable int uid,@PathVariable int id){
        
        System.out.println("id:"+id);
        System.out.println("uid:"+uid);
        return "/index.jsp";
    }

3.同一个controller通过参数来到达不同的处理方法--不重要
