Front와 Back 따로!
Backend(Server) - STS
STS 설정
1. 프로젝트 생성
boot
2. pom.xml에 spring boot start web + spring boot starter tomcat 추가

3. src/main/resources의 application.properties에 포트 설정
4. Controller 설정
package bit.com.a.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController // == @Controller + @Responsebody => Restful
public class HelloController {
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String test() throws Exception{
System.out.println("test()");
return "test";
}
}
5. 클라이언트에서 접속할 수 있도록 WebConfig 보안 설정
package bit.com.a;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
// TODO Auto-generated method stub
// WebMvcConfigurer.super.addCorsMappings(registry);
registry.addMapping("/**").allowedOrigins("http://localhost:8060");
}
}
" 8060 포트에서 온 host는 허용해주어라!! "
Client(Front) - Eclipse
1. index.html 파일로 만들어준다. jsp 파일 아님!
2. 작성하고 Ajax 로 데이터 보내보기
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
<p id="demo"></p>
<button type="button">click</button>
<script type="text/javascript">
$(document).ready(function () {
$("button").click(function() {
// alert('click');
$.ajax({
url:"http://localhost:3010/test",
type:'get',
success:function(data){
// alert('success');
// alert(data);
$("#demo").text(data);
},
error:function(){
alert('error');
}
});
});
});
</script>
</body>
</html>
클릭시 Controller에서 설정해주었던 test라는 글자가 뜨면 성공!
