MVC: Model, View, Controller
@Controller
public class HelloController {
@GetMapping("hello-mvc")
public String helloMvc(@RequestParam("name") String name, Model model) {
model.addAttribute("name", name);
return "hello-template";
}
}
// resources/templates/hello-template.html
<html xmlns:th="http://www.thymeleaf.org">
<body>
<p th:text="'hello ' + ${name}">hello! empty</p>
</body>
</html>


@Controller
public class HelloController {
@GetMapping("hello-string")
@ResponseBody
public String helloString(@RequestParam("name") String name) {
return "hello " + name;
}
}
@ResponseBody 를 사용하면 뷰 리졸버( viewResolver )를 사용하지 않음
@Controller
public class HelloController {
@GetMapping("hello-api")
@ResponseBody
public Hello helloApi(@RequestParam("name") String name) {
Hello hello = new Hello();
hello.setName(name);
return hello;
}
static class Hello {
private String name;
public String getName;
return name;
}
public void setName(String name) {
this.name = name;
}
}
}


@ResponseBody 를 사용viewResolver 대신에 HttpMessageConverter 가 동작StringHttpMessageConverterMappingJackson2HttpMessageConverter
