在 Tomcat 中部署 Spring 引导应用程序 6（传统部署）

Question

我试图在 tomcat 6 中部署一个 spring 引导应用程序 (war)（当在 tomcat 7 及更早版本中部署时我没有问题），事实上，使用 新方式 无法在 tomcat 6 (servlet 2.5) 中部署（我会将描述新方式的 link 放在底部）因为 Spring Boot 使用 Servet 3.0 API 来初始化 ServletContext（注册 Servlet 等），所以您不能在 Servlet 2.5 容器中使用开箱即用的相同应用程序。

我在文档中找到的部署在 spring 中的解决方案（我将把 link 放在底部）是添加 web.xml.

现在，当我在部署后发送请求时出现此错误：

我在文档中使用相同的 web.xml :

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>sofadev.docapost.phenix.server.changedot</param-value>
</context-param>

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

<filter>
    <filter-name>metricFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>metricFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<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>

当然还有 pom.xml:

    <artifactId>spring-boot-starter-parent</artifactId>

Answer 1

您试图部署到 Tomcat6，这违反了 Spring 启动要求。即使您破解应用程序以启动某些内容，以后也可能会出现问题。因为你在 Spring Boot 1.5.9.RELEASE the docs mention it clearly:

Tomcat 7 & 8.0 work with Spring Boot, but the default is to use Tomcat 8.5. If you cannot use Tomcat 8.5 (for example, because you are using Java 1.6) you will need to change your classpath to reference a different version.

Tomcat 6 是遗留的，运行这是一个安全风险。 It's security support ended on 31 December 2016 and you can't download it since 30 March 2017。升级您的 Tomcat 版本。
