Tomcat 6.0.35 和 java 8

【问题描述】：

我正在尝试将 Spring Boot 应用程序部署到 Tomcat 6.0.35。

我从www.mkyong.com 下载了示例应用程序并构建了.war 应用程序。我把它移到了 tomcat webapps 目录。

我可以访问tomcat 6主页，和管理器，甚至部署应用程序，但是当我转到http://localhost:8080/demo-0.0.1-SNAPSHOT时，我得到404页面。

我没有收到任何错误，见下文：

在 tomcat 8 上部署可以正常工作，但不幸的是我必须使用 tomcat 6.0.35。

我正在使用 java 1.8.0_121-b13 oracle。

我是否遗漏了一些额外的配置？

【问题讨论】：

  • 您正在将 Spring Boot 应用程序部署到不支持 Servlet 3.0 的容器中，因此它将无法工作，您至少需要一个支持 Servlet 3.0 的容器或使用 Spring Boot Legacy 来引导Servlet 2.5 环境中的 Spring Boot 应用程序。
  • 正确的路径是 apache-tomcat/webapps，我可以看到 war 文件和解压文件，但我认为 @M.Deinum 发布了正确的解决方案。我会检查它，并会提供反馈。

【解决方案1】：

我添加 spring-boot-legacy 依赖：

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-legacy -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-legacy</artifactId>
            <version>1.1.0.RELEASE</version>
        </dependency>

然后我在 webapp/WEB-INF/ 目录下创建 web.xml 并填写：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>com.mkyong.SpringBootWebApplication</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.boot.legacy.context.web.SpringBootContextLoaderListener</listener-class>
    </listener>


    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextAttribute</param-name>
            <param-value>org.springframework.web.context.WebApplicationContext.ROOT</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

最后是 /logs/ 中的 catalina.out 文件：
