Springboot全局异常处理

spring-boot-devtools的范围设置为provided，打包的时候不会打包这个jar包，防止异常时泄露信息，具体见参考连接。

server.servlet.context-path的值为/api时，如果访问的地址不是以api开头将不会进入到异常捕捉。所以最好是为/

server.servlet.context-path=/api
spring.jackson.default-property-inclusion=non_null
spring.mvc.throw-exception-if-no-handler-found=true
spring.web.resources.add-mappings=false

@Slf4j
@ResponseBody
@ControllerAdvice
public class GlobalExceptionHandler {

	@ExceptionHandler(value = Exception.class)
	public Result exceptionHandler(HttpServletRequest httpServletRequest, Exception e) {
		log.error("内部错误", e);
		return new Result(500, "Internal Server Error", null);
	}

}

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Result {

	private int code;
	private String message;
	private Object data;

}

@RestController
@RequestMapping("test")
public class TestController {

	@RequestMapping
	public @ResponseBody Result test() {
		return new Result(200, "OK", null);
	}

}
