### 一、控制器 ###

@RestController
    @RequestMapping("test")
    public class TestController {
        
    
    	/**
         * 用来测试表单参数传递：单个参数
         */
    	@PostMapping(value = "/formDataTest")
    	public Object formDataTest(@RequestParam String id) {
        
    		......
    	}
    	
    	/**
         * 用来测试表单参数传递：多个参数
         */
    	@PostMapping(value = "/formDataTest2")
    	public Object formDataTest2(@RequestParam String id, @RequestParam String name) {
        
    		......
    	}
    
    	/**
         * 用来测试Json参数传递
         */
    	@PostMapping(value = "/jsonTest")
    	public Object jsonTest(@RequestBody JsonTestParam param) {
        
    		......
    	}
    	
    	 /**
         * 用来测试HttpServletRequest参数传递
         */
    	@PostMapping(value = "/httpServletRequest_Test")
    	public Object httpServletRequest_Test(HttpServletRequest request) {
        
    		......
    	}
    }

### 二、Feign客户端 ###

@FeignClient(name = "defaultXXX-cloud", contextId = "XXXClient", path = "defaultXXXPath")
    @RefreshScope
    public interface XXXFeignClient {
        
    
    	/**
         * 传递表单参数：单个参数
         */
        @PostMapping(value = "/test/formDataTest")
        Object formDataTest(String id);
    
    	/**
         * 传递表单参数：多个参数，需要使用@RequestParam并指定name属性，否则会报错
         */
        @PostMapping(value = "/test/formDataTest2")
        Object formDataTest2(@RequestParam(name = "id") String id, @RequestParam(name = "name") String name);
    
    
    	/**
         * 传递JSON参数方式一：指定：consumes = "application/json"
         */
        @PostMapping(value = "/test/jsonTest", consumes = "application/json")
        Object jsonTest(JsonTestParam param);
    
    	/**
         * 传递JSON参数方式二：使用@RequestBody
         */
        @PostMapping(value = "/test/jsonTest")
        Object jsonTest(@RequestBody JsonTestParam param);
    
    
    	/**
         * 传递HttpServletRequest：不需要传递，直接调用即可
         */
    	@PostMapping(value = "/test/httpServletRequest_Test")
        Object httpServletRequest_Test();
    
    }
