在Tomcat 6中部署Spring Boot应用程序（传统部署）

Question

我试图在tomcat 6中部署一个Spring引导应用程序（战争）（当在tomcat 7和更旧的版本中部署时，我没有问题），事实上在tomcat 6（servlet 2.5）中部署是不可能使用新的方式（我会把描述新方式的链接放在底部），因为Spring Boot使用Servet 3.0 API初始化ServletContext（注册Servlet等），所以您不能在Servlet 2.5容器中开箱即用地使用相同的应用程序。

我在文档中找到的在spring中部署的解决方案（我将把链接放在底部）是添加web。xml。

现在，当我在部署后发送请求时，会出现以下错误：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'metricFilter' available

我在留档中使用相同的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Tomcat 6，这违反了Spring Boot的要求。即使你黑客攻击你的应用程序来启动一些东西，以后可能会崩溃。因为你在Spring Boot 1.5.9上。发布文件时要清楚地提到：

Tomcat 6是遗留的，运行它会带来安全风险。它的安全支持已于2016年12月31日结束，自2017年3月30日起无法下载。升级你的Tomcat版本。
