java - 如何在 Spring Boot 中调试请求？

问题描述

我的电脑重新启动，我的应用程序今天不再工作。昨天还在工作。除了 Maven 下载新库（主要是亚马逊）之外，什么都没有改变。现在我什至无法访问该/admin/login页面。如何调试请求？

2019-09-13 17:26:16.924  INFO 2056 --- [  restartedMain] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/admin/login],methods=[GET]}" onto public java.lang.String com.s.s.controller.Controller.login()
2019-09-13 17:26:21.465 ERROR 2056 --- [nio-8080-exec-1] c.s.s.c.Controller     : invalidRequest(): invalid request: /admin/login

@RequestMapping(value="/admin/login", method=RequestMethod.GET)
public String login() {
    return "login";
}
@RequestMapping("/error")
public void invalidRequest(HttpServletRequest request, HttpServletResponse response){

    Logger.error(TAG, "invalidRequest()", "invalid request: " + request.getAttribute(RequestDispatcher.FORWARD_REQUEST_URI));
    try {
        response.setStatus(HttpStatus.OK.value());
        response.getWriter().write("This is not a valid request");
    } catch (IOException e) {
        Logger.error(TAG, "invalidRequest: ", "Exception in invalidRequest() method "+e.getMessage());
    }
}
@Override
public String getErrorPath() {
    return "/error";
}

我设置了这条线，application.properties但它没有打印任何额外的东西。

logging.level.com.s.s.controller.Controller=DEBUG

我运行mvn clean并重新启动服务器，但它没有帮助。

我设置了这条线，application.properties但它没有打印任何有用的东西。

debug=true

$ git status

        modified:   src/main/resources/static/js/home.js

我将库与上次部署的库进行了比较，唯一的变化是

aws-java-sdk-core-1.11.631.jar
aws-java-sdk-kms-1.11.631.jar
aws-java-sdk-s3-1.11.631.jar
aws-java-sdk-ses-1.11.631.jar
jmespath-java-1.11.631.jar

我评论了public String getErrorPath()，public void invalidRequest()现在它给了我

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Forbidden, status=403).
No message available

但是有了curl它

$ curl localhost:8080/admin/login
{"timestamp":1568401131164,"status":403,"error":"Forbidden","message":"No message available","path":"/admin/login"}

我在 Makgigrahul 的回答中找到了以下搜索spring-sleuth并将其添加到application.properties生成此日志中。

logging.level.org.springframework.web.servlet.DispatcherServlet=DEBUG

解决方案

您可以尝试在 org.apache.catalina.core.ApplicationFilterChain#doFilter 中设置断点。这在请求处理的开始就很漂亮。或者你可以看看 org.springframework.web.servlet.DispatcherServlet#doDispatch
