当战争部署在外部Tomcat中时，Springboot端点失败

[英]Springboot endpoint fails when the war is deploy in an external Tomcat

 原文  2018-01-25 20:25:57  4   1    java/ tomcat/ spring-boot

问题描述

我正在使用springboot 1.5.9，Tomcat的外部版本是8.5.7。 首先，我使用Spring Initializr生成初始包，而不选择任何选项。 创建类控制器并编写一个带有端点的方法（Get方法）之后，该方法返回一个String。 

package com.test;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @RequestMapping(value = "/test")
    public String index() {

       return "REST API HERE ";
    }

}

如果我运行带有嵌入式tomcat的api并与邮递员进行通话，则一切正常。

使用嵌入式tomcat与邮递员一起测试

之后，我产生战争（使用软件包）并放入外部tomcat中。 当tomcat部署战争时，没有错误。

但是，当我用邮递员做同样的文字时，我收到404错误：

我迷路了，因为我不知道问题出在外部的tomcat配置还是springboot软件包。

我检查了很多东西：

  1. 我按照所有步骤使用springboot部署外部战争（实际上，战争部署没有错误），就像该文档所示： https : //docs.spring.io/spring-boot/docs/current/reference/html/howto -传统- deployment.html

  2. 我检查了外部tomcat中的端口8080是否打开。

  3. 我在不同的tomcats中进行了测试（一个在Windows中，两个在Linux中）。

  4. 我检查了Java版本。

但是似乎没有任何作用。

如果您需要更多信息，请询问我。 谢谢您的帮助！

我在test / src / main / webapp / WEB-INF / web.xml中添加了以下web.xml。 但是问题仍然存在。

默认情况下，Tomcat将使用WAR的名称作为将应用程序部署到的上下文。 在您的情况下，上下文名称将为test-0.0.1-SNAPSHOT因此访问您的应用程序的URL将为http：// localhost：8080 / test-0.0.1-SNAPSHOT / 。

如果您希望将应用程序部署到根目录，则可以将文件ROOT.war 。 您还可以在context.xml文件中指定其他上下文名称（战争中包含或包含在外部）。

在此处查看有关上下文的Tomcat文档
