Spring Boot嵌入式Tomcat'allowLinking'屬性

Question

我一直在尋找一種方法來公開屬性'allowLinking'，以允許TomcatEmbeddedServletContainerFactory遵循符號鏈接到其documentRoot下的資源。

根據Tomcat 8 Migration文檔，此功能切換到Tomcat 8+的“Resources”標簽： Tomcat 8遷移指南

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

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

如何以編程方式為Spring Boot應用程序配置TomcatEmbeddedServletContainerFactory時如何公開此屬性？

Answer 1

我有完全相同的問題，並能夠實現以下解決此問題：

@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;
}

Answer 2

在Tomcat 8中修改代碼的Erik Brandsberg解決了這個問題

@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;
}
