Question

我正在编写Java Spring MVC应用程序。当我检查了网址（http://localhost:8080/ui/processes）时，它没有呈现视图，而是抛出这样的异常：

java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "getClassLoader")

at javax.servlet.http.HttpServlet.service(HttpServlet.java:848)

我的web.xml：

<servlet>
    <servlet-name>static</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>static</servlet-name>
    <url-pattern>/ui/*</url-pattern>
</servlet-mapping>

static-servlet.xml：

<context:component-scan base-package="com.myproject.service.mypackage" />

<bean class = 
"org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name = "prefix" value = "/jsp/" />
    <property name = "suffix" value = ".jsp" />
</bean>

控制器：

@Controller
@RequestMapping("/processes")
public class ProcessesController {

@RequestMapping(method = RequestMethod.GET)
public ModelAndView printProcesses(){
    ModelAndView model = new ModelAndView("Processes");
    model.addObject("msg", "hello process");
    return model;
}
}

Process.jsp是一个简单的html文件

<html>
<head>
    <title> Process </title>
</head>
<body>
    <h1> HAHAHAHA!!!! </h1>
</body>
</html>

我是Spring MVC的新手，所有步骤都遵循教程。任何人都知道是什么导致了上述异常以及如何解决它？

java.security.AccessControlException：拒绝访问（“java.lang.RuntimePermission”“getClassLoader”）
