Spring MVC - Servlet调度器抛出异常：java.lang.StackOverflowError

我有一个工作的AngularJS + Spring MVC应用程序叫做A.这个web应用程序已被克隆（ctrl + c & ctrl + v在项目文件夹中） B.Spring MVC - Servlet调度器抛出异常：java.lang.StackOverflowError

试图运行它们（自然地）具有相同的行为。

我的目标是简化A，但是我在第一步就陷入了困境，我希望做的是对包含.html文件的文件夹进行一些重构。

树的文件夹如下：

src/main/webapp 
      |--- WEB-INF/ 
      |--- META-INF/ 
      |--- static/ 
        |--- js/ 
        |--- css/ 
        |--- index.html 
        |--- sth.html

转型的B是：

src/main/webapp 
      |--- META-INF/ 
      |--- js/ 
      |--- css/ 
      |--- index.html 
      |--- sth.html

简单地说，我把里面的文件夹static一个级别的所有资源。

下一步就是要适应在A WebMvcConfigurerAdapter从旧的一个开始（是的，我会做一个更好的组织代码，一旦解决... ARG !!!）：

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "my.package.name") 
public class Configurations extends WebMvcConfigurerAdapter { 

    @Override 
    public void configureViewResolvers(ViewResolverRegistry registry) { 
     InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
     viewResolver.setViewClass(JstlView.class); 

     viewResolver.setPrefix("/static/"); 
     viewResolver.setSuffix(".html"); 

     registry.viewResolver(viewResolver); 
    } 

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     //resources locations 

     // html 
     registry.addResourceHandler("static/**").addResourceLocations("/static/"); 
     registry.addResourceHandler("static/modals/**").addResourceLocations("/static/modals/"); 

     // css 
     registry.addResourceHandler("css/**").addResourceLocations("/static/css/"); 
     registry.addResourceHandler("css/bootstrap/**").addResourceLocations("/static/css/bootstrap/"); 
     registry.addResourceHandler("js/fullcalendar/dist/**").addResourceLocations("/static/js/fullcalendar/dist/"); 

     // scripts 
     registry.addResourceHandler("js/**").addResourceLocations("/static/js/"); 
     registry.addResourceHandler("js/jquery/**").addResourceLocations("/static/js/jquery/"); 
     registry.addResourceHandler("js/bootstrap/**").addResourceLocations("/static/js/bootstrap/"); 
     registry.addResourceHandler("js/bootstrap/ui-bootstrap/**").addResourceLocations("/static/js/bootstrap/ui-bootstrap/"); 
     registry.addResourceHandler("js/bootstrap/umd/**").addResourceLocations("/static/js/bootstrap/umd/"); 
     registry.addResourceHandler("js/angular/**").addResourceLocations("/static/js/angular/"); 
     registry.addResourceHandler("js/angular/animate/**").addResourceLocations("/static/js/angular/animate/"); 
     registry.addResourceHandler("js/angular/ui-router/release/**").addResourceLocations("/static/js/angular/ui-router/release/"); 
     registry.addResourceHandler("js/angular-ui-calendar/src/**").addResourceLocations("/static/js/angular-ui-calendar/src/"); 
     registry.addResourceHandler("js/fullcalendar/dist/**").addResourceLocations("/static/js/fullcalendar/dist/"); 
     registry.addResourceHandler("js/moment/**").addResourceLocations("/static/js/moment/"); 
     registry.addResourceHandler("js/angular-ui-grid/**").addResourceLocations("/static/js/angular-ui-grid/"); 

     // custom 
     registry.addResourceHandler("js/service/**").addResourceLocations("/static/js/service/"); 
     registry.addResourceHandler("js/controller/**").addResourceLocations("/static/js/controller/"); 
     registry.addResourceHandler("js/controller/modals/**").addResourceLocations("/static/js/controller/modals/"); 
    } 

}

到一个新的一个用于B：

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "my.package.name") 
public class Configurations extends WebMvcConfigurerAdapter { 

    @Override 
    public void configureViewResolvers(ViewResolverRegistry registry) { 
     InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
     viewResolver.setViewClass(JstlView.class); 

     viewResolver.setPrefix("/"); 
     viewResolver.setSuffix(".html"); 

     registry.viewResolver(viewResolver); 
    } 

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     //resources locations 

     // html 
     registry.addResourceHandler("/**").addResourceLocations("/"); 

     // css 
     registry.addResourceHandler("/css/**").addResourceLocations("/css/"); 
     registry.addResourceHandler("/css/bootstrap/**").addResourceLocations("/css/bootstrap/"); 
     registry.addResourceHandler("/js/fullcalendar/dist/**").addResourceLocations("/js/fullcalendar/dist/"); 

     // scripts 
     registry.addResourceHandler("/js/**").addResourceLocations("/js/"); 
     registry.addResourceHandler("/js/jquery/**").addResourceLocations("/js/jquery/"); 
     registry.addResourceHandler("/js/bootstrap/**").addResourceLocations("/js/bootstrap/"); 
     registry.addResourceHandler("/js/bootstrap/ui-bootstrap/**").addResourceLocations("/js/bootstrap/ui-bootstrap/"); 
     registry.addResourceHandler("/js/bootstrap/umd/**").addResourceLocations("/js/bootstrap/umd/"); 
     registry.addResourceHandler("/js/angular/**").addResourceLocations("/js/angular/"); 
     registry.addResourceHandler("/js/angular/animate/**").addResourceLocations("/js/angular/animate/"); 
     registry.addResourceHandler("/js/angular/ui-router/release/**").addResourceLocations("/js/angular/ui-router/release/"); 
     registry.addResourceHandler("/js/angular-ui-calendar/src/**").addResourceLocations("/js/angular-ui-calendar/src/"); 
     registry.addResourceHandler("/js/fullcalendar/dist/**").addResourceLocations("/js/fullcalendar/dist/"); 
     registry.addResourceHandler("/js/moment/**").addResourceLocations("/js/moment/"); 
     registry.addResourceHandler("/js/angular-ui-grid/**").addResourceLocations("/js/angular-ui-grid/"); 

     // custom 
     registry.addResourceHandler("/js/service/**").addResourceLocations("/js/service/"); 
     registry.addResourceHandler("/js/controller/**").addResourceLocations("/js/controller/"); 
    } 

}

所示形式，我删除每条路径上static/前缀。

一旦运行，递归浏览器的控制台给我Error 500请求sth尽管成功地给我index.html

GET http://localhost:8080/MyWebApp/sth 500 (Internal Server Error)

而Tomcat正在记录此之外，所有时间长：

//To the infinity and beyond! (cit.)... unless tomcat shutdown

这是索引控制器：

@Controller 
@RequestMapping("/") 
public class IndexController { 

    @RequestMapping(method = RequestMethod.GET) 
    public ModelAndView getIndexPage() { 
     return new ModelAndView("index"); 
    } 

}

控制器来管理sth页面

@Controller 
public class TemplateController { 

    @RequestMapping(value = "/sth") 
    public ModelAndView getGrid() { 
     return new ModelAndView("sth"); 
    } 

}

angular.ui路由器内app.js文件：

var app = angular.module('MyWebApp', [ 
    'ui.router', 
    'ui.calendar', 
    'ngAnimate', 
    'ui.bootstrap', 
    'ui.grid' 
]); 

//globals 
app.value('baseUrl', '/MyWebApp'); 

app.config(function ($stateProvider, $urlRouterProvider) { 

    $urlRouterProvider.otherwise('/sth'); 

    $stateProvider.state('sth', { 
     url: '/sth', 
     templateUrl: 'sth', 
     controller: 'sthCtrl', 
     controllerAs: 'sth' 
    }); 

});

，最后的sthCtrl文件

app.controller('sthCtrl', function ($http, baseUrl) { 
    var scope = this; 
    scope.users = []; 
    scope.structures = []; 

    $http.get(baseUrl + '/users').then(function (userResp) { 
     scope.users = userResp.data; 
    }); 

    $http.get(baseUrl + '/structures').then(function (structureResp) { 
     scope.structures = structureResp.data; 
    }); 

});

我一定是错过了一些东西，我看不到...但是，我有一些嫌疑人：

1）在Configurations课程中：我可以忘记一些东西; 2）这是一个前端结构性问题：创建static文件夹并移动所有以前的人群（改变路径Configurations类）“自动”Error 500消失，我可以看到我的HTML！（OMG），所以我猜如果AngularJS需要static文件夹，并且如果我不想要，我必须在某种程度上告诉它...但是Tomcat的例外仍然是（废话...）

对于AngularJS和Spring MVC都没有什么经验，我无法弄清楚我错过了什么。

尝试改变sth.html的名称别的东西和唐忘记改变它也在控制器中返回新的ModelAndView（“sth”）; – reos

其实'sth'是我在这个线程中使用的通用占位符，但实际上它的名字是'grid'，因为那个页面显示了一个表格。 – grimi

我问你这是因为你的@RequestMapping（value =“/ sth”） public ModelAndView getGrid（）{ return new ModelAndView（“sth”）; }我想这可能会导致无穷无尽。 – reos

您需要返回将由ViewResolver被解析为View一个字符串，尝试这样的事情，以避免你的无限循环：

@RequestMapping(value = "/sth") 
    public String getGrid() { 
    return "someThing"; 
}

其实我没有web.xml。我在A和B应用程序上都使用了带注释的Spring。 – grimi
