Question

我一直在寻找一种方法来公开属性'allowLinking'，以允许TomcatEmbeddedServletContainerFactory遵循符号链接到其documentRoot下的资源。

根据Tomcat 8 Migration文档，此功能已切换为Tomcat 8+的“Resources”标记：Tomcat 8 Migration Guide

<!-- Tomcat 7: -->
<Context allowLinking="true" />

<!-- Tomcat 8: -->
<Context>
  <Resources allowLinking="true" />
</Context>

如何以编程方式为Spring Boot应用程序配置TomcatEmbeddedServletContainerFactory时如何公开此属性？

Answer 1

我有完全相同的问题，并且能够实现以下解决方法：

@Bean
public EmbeddedServletContainerFactory servletContainer() 
{
    TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
    // allow symbolic links under the filesystem context
    // don't use this on Windows!
    if (IOCase.SYSTEM.isCaseSensitive())
    {
        Log.info("Enabling support for symbolic links on the webserver.");
        for (TomcatContextCustomizer customizer : tomcat.getTomcatContextCustomizers())
        {
            StandardContext context = new StandardContext();
            context.setAllowLinking(true);
            customizer.customize(context);
        }
    }
    return tomcat;
}

在Tomcat 8中修改代码的Erik Brandsberg解决了这个问题

@Bean
public EmbeddedServletContainerFactory servletContainer()
{
    TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
    // allow symbolic links under the filesystem context
    // don't use this on Windows!
    if (IOCase.SYSTEM.isCaseSensitive())
    {
        TomcatContextCustomizer customizer = new TomcatContextCustomizer() {
            @Override
            public void customize(Context context) {
                StandardRoot r = new StandardRoot();
                r.setAllowLinking(true);
                context.setResources(r);
            }
        };
        tomcat.addContextCustomizers(customizer);

    }
    return tomcat;
}

Spring Boot嵌入式Tomcat'allowLinking'属性
