SpringMVC

1、RequestMapping 处理地址映射请求

    参数： value, produces, method, params, headers

    value:指定请求的实际地址

    1、最基本

@RequestMapping(value="/departments")  public String simplePattern(){        System.out.println("simplePattern method was called");      return "someResult";  }

  通过访问 http://localhost:8080/***/departments，可以进入函数

  2、绑定参数

@RequestMapping(value="/departments")      public String findDepatment(        @RequestParam("departmentId") String departmentId){                  System.out.println("Find department with ID: " + departmentId);          return "someResult";            }

 

  形如这样的访问形式：

   /departments?departmentId=23就可以触发访问findDepatment方法了

3 REST风格参数

RequestMapping(value="/departments/{departmentId}")  public String findDepatment(@PathVariable String departmentId){      System.out.println("Find department with ID: " + departmentId);    return "someResult";    }

形如REST风格的地址访问，比如：

/departments/23，其中用(@PathVariable接收rest风格的参数
