SpringBoot基础操作

一、获取url请求参数三种方法

注：前两种方法都使用了json打印，也可以手动打印，我这边用fastjson方便一点

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.58</version>
        </dependency>

1、使用HTTPServletRequest获取

    @RequestMapping("index")
    @ResponseBody
    public String index(HttpServletRequest request){
        System.out.println(JSON.toJSONString(request.getParameterMap()));
        return JSON.toJSONString(request.getParameterMap());
    }

该方法需要引入Servlet包

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
        </dependency>

2、使用RequestParam注解获取

    @RequestMapping("index2")
    @ResponseBody
    public String index2(@RequestParam Map<String,String> paramMap){
        System.out.println(JSON.toJSONString(paramMap));
        return JSON.toJSONString(paramMap);
    }

2、使用AOP切面获取

需要引入切面包

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

@Component
@Aspect
public class WebControllerAop {


    @Pointcut("execution(* com.example..*(..))")
    public void executeService(){

    }

    @Before("executeService()")
    public void doBeforeAdvice(JoinPoint joinPoint) {
        for (Object object : joinPoint.getArgs()) {
            System.out.println("类路径："+joinPoint.getTarget().getClass().getName() +
                    "." +
                    joinPoint.getSignature().getName() +
                    " : 请求参数 : " +
                    object.toString());
        }
    }
}

注：我这里使用第一种一直获取不到，后来发现是引入web包错误

 

 

    @RequestMapping("EPGModifiedInf")
    @ResponseBody
    public Map<String, Object> EPGModifiedInf(@RequestParam(required=false) Map<String, String> urlParams ,
                                     @RequestBody(required=false) Map<String, Object> bodyParams){
        log.info(" EPGModifiedInf  进入 ");
        if(urlParams!=null && urlParams.size()>0){
            log.info("  EPGModifiedInf urlParams 请求参数为："+JSON.toJSONString(urlParams));
        }
        if(bodyParams!=null && bodyParams.size()>0){
            log.info("  EPGModifiedInf bodyParams 请求参数为："+JSON.toJSONString(bodyParams));
        }
        Map<String,Object > map = new HashMap<>();
        map.put("code",0);
        map.put("msg","Success");
        log.info(" EPGModifiedInf  出去 ");
        return map;
    }
