Spring boot 如何使用spring boot禁用tomcat清单扫描？

我们有一个依赖项（JAR），它确实包含一个清单文件，引用它的

类路径

条目中的其他JAR。应用程序不需要这些引用的其他JAR，因此不作为依赖项添加

当应用程序启动时，tomcat会尝试解析该类路径条目，最终会在日志中出现大量错误。比如：

如本文所述，Tomcat实现了一个开关，用于禁用清单扫描以防止此问题：

在正常的tomcat安装中，我们可以这样做（）：

如何使用spring boot禁用tomcat清单扫描？

您可以选择底部

@Bean
public TomcatServletWebServerFactory tomcatFactory() {
   return new TomcatServletWebServerFactory() {
      @Override
      protected void postProcessContext(Context context) {
         ((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
   }};
}

你可以喜欢底部

@Bean
public TomcatServletWebServerFactory tomcatFactory() {
   return new TomcatServletWebServerFactory() {
      @Override
      protected void postProcessContext(Context context) {
         ((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
   }};
}
