SpringMVC控制器接受各类请求参数

1. 普通参数和pojo可以通过参数直接传入控制器，前提是名称相同。
2. @RequestParam注解获取参数

@Controller
@RequestMapping("/params")
public class ParamsController {
    @RequestMapping("/commonParams")
    public ModelAndView commonParams(@RequestParam("role_name") String rolename){
        System.out.println("rolename:"+rolename);
        RoleParams params = new RoleParams();
        params.setRolename("hello");
        params.setNote("note");
        ModelAndView mv = new ModelAndView();
        mv.addObject(params);
        mv.setView(new MappingJackson2JsonView());
        return mv;
    }
}

3. 使用URL获取参数@PathVariable

@Controller
@RequestMapping("/params")
public class ParamsController {
    @RequestMapping("/commonParams/{name}")
    public ModelAndView commonParams(@PathVariable("name") String rolename){
        System.out.println("rolename:"+rolename);
        RoleParams params = new RoleParams();
        params.setRolename("hello");
        params.setNote("note");
        ModelAndView mv = new ModelAndView();
        mv.addObject(params);
        mv.setView(new MappingJackson2JsonView());
        return mv;
    }
}
