[Spring] 로그, 한글 filter 적용, RequestMapping 관련, ajax

1. 로그

예제) TestController.java

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

private static final Logger logger = LoggerFactory.getLogger(TestController.class);

@GetMapping("/list")

public String testList() {

logger.info("TestController, testList.");

return "test/testList";

}

 

2. 필터 설정

Project -> src -> main -> web.xml

<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

아랫부분에 추가

<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

반응형

3. @RequestMapping 편리한 방법

기존_) @RequestMapping(value = "/", method = RequestMethod.GET)

or

추가 _) @GetMapping

 

4. ajax

$.ajax({

type : "타입"

, url : "url"

, data : "데이터"

, contentType : "형식"

, success : "성공"

, error : "에러"

});

 

ex)

ajax ({

type : "put"

, url : "/test/detail/put"

, data : JSON.stringify(jsonData)

, contentType : "application/json; charset=utf-8"

, success : function(result) {

if (result == "SUCCESS") {

alert ("전송에 성공하였습니다.");

}

, error : function(error) {

alert("전송에 실패하였습니다.");

}

});
