java - 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 boot 应用程序(war)(当在 tomcat 7 和更早版本中部署时我没有问题)，实际上在 tomcat 6(servlet 2.5)中部署是不可能使用的新方式(我会将描述新方式的链接放在底部)因为 Spring Boot 使用 Servet 3.0 API 来初始化 ServletContext(注册 Servlet 等)所以你不能使用相同的应用程序Servlet 2.5 容器中的盒子。

我在文档中找到的spring部署的解决方案(我会把链接放在底部)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

您通过尝试部署到 Tomcat 6 违反了 Spring Boot 要求。即使您破解您的应用程序以启动某些内容，以后也可能会出现问题。由于您使用的是 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 是旧版，运行它存在安全风险。 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。
