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
