HTTP状态500 -Javax.Servlet.ServletException:Servlet执行抛出了例外

Question

我正在使用Spring MVC和AngularJS开发动态Java项目。该项目在Ubuntu系统上成功运行。但是在Windows中，这个项目没有运行。

我正在使用tomcat 7. lib文件夹下的所有必需罐子。成功构建项目后，它会引发异常。

我检查了有关堆栈溢出的相关问题，但我的问题没有重新解决。我试图将这个问题重新融化超过一个星期，但我无法重新涂这个问题。

谢谢你，看起来积极重播..！

Answer 1

您正在遇到递归环。一个例子是(伪代码(：

void causeStackOverflow() {
    if (a == b) { // which is never the case
        return;
    } else {
        causeStackOverflow();
    }
}

基本上，您必须找出为什么在httpservletrequestwrapper.java上使用的代码在第184行上一次又一次地调用，并在此处修复您的代码逻辑。

如果您想对此有所帮助，则必须发布代码

Answer 2

配置springmvc时，我发现不添加JSTL的maven依赖关系至少会导致此问题，但我不知道您是否是是同一错误。查看解析器问题
