@Controller와 @RestController를 같이 사용하기
2024. 5. 26. 00:35ㆍJava/Spring Boot
@Controller와 @RestController를 같이 사용하면, @Controller가 작동하지 않음
@Controller 사용
# Main.java
@Controller
public class Main {
@RequestMapping("/a")
public String deGetHelloWorld() {
System.out.println("ssssssssssssssssssssssssss");
return "Hello World";
}
@GetMapping("/")
public String home() {
return "home";
}
}
# /src/main/resources/templates/home.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org">
<head>
<title>Spring Security Example</title>
</head>
<body>
<h1>Welcome!</h1>
<p>Click <a th:href="@{/hello}">here</a> to see a greeting.</p>
</body>
</html>
@RestController 사용
# Main.java
@RestController
public class Main {
@RequestMapping("/a")
public String deGetHelloWorld() {
System.out.println("ssssssssssssssssssssssssss");
return "Hello World";
}
@GetMapping("/")
public String home() {
return "home";
}
}
# /src/main/resources/templates/home.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org">
<head>
<title>Spring Security Example</title>
</head>
<body>
<h1>Welcome!</h1>
<p>Click <a th:href="@{/hello}">here</a> to see a greeting.</p>
</body>
</html>
에러가 안나도록 조치
# Main.java
@Controller
public class Main {
@RequestMapping("/a")
public @ResponseBody String deGetHelloWorld() {
System.out.println("ssssssssssssssssssssssssss");
return "Hello World";
}
@GetMapping("/")
public String home() {
return "home";
}
}
# /src/main/resources/templates/home.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="https://www.thymeleaf.org">
<head>
<title>Spring Security Example</title>
</head>
<body>
<h1>Welcome!</h1>
<p>Click <a th:href="@{/hello}">here</a> to see a greeting.</p>
</body>
</html>
