SpringBoot 处理全局异常

使用 @ControllerAdvice 声明并用 @ExceptionHandler 声明需要捕获的异常。

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Map;

@RestController
@ControllerAdvice
public class GlobalControllerExceptionHandler {

    @ExceptionHandler(value = Exception.class)
    public Map defaultErrorHandler(HttpServletRequest request, HttpServletResponse response, Exception e) {
        // 省略部分代码
    }

}
