Java 春堂'；看不见控制器

我的spring MVC应用程序有问题。当我尝试在弹簧控制器和角度控制器之间传递数据时，我的应用程序看不到我的控制器

弹簧配置：

My controller.js

"use strict"

PiManager.controllers = {};

PiManager.controllers.main =
['mainService', '$scope', '$state', '$http', function(mainService, $scope, $state, $http) {

$scope.getTest = function(id) {
    mainService.getTestEntity(id).then(function(response) {
        $scope.testEntityPart = response;
    });
}

}];
 app.controller('mainController', PiManager.controllers.main);

我的spring主控制器

@Controller
@RequestMapping("/PiManager/")
public class MainController {

@Autowired
private TestEntityRepository testEntityRepository;

@RequestMapping(value = "/main")
public String index() {
    return "/index.jsp";
}

@ResponseBody
@RequestMapping(value = "/index/{id}", method = RequestMethod.GET)
public List<TestEntity> getTestEntity(@PathVariable("id") Long id) {
    return testEntityRepository.findById(id);
}
}

我真的不知道该怎么做才能让它工作。

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

调度员
/*

您将查找正确的

@控制器的调度程序配置为仅接受xml中的
*.html
。试试
/*
：还是什么都没有。现在我得到了警告o.s.web.servlet.PageNotFound-在名为“dispatcher”的DispatcherServlet中找不到URI为[/PiManager/main]的HTTP请求的映射
@Controller
@RequestMapping("/PiManager/")
public class MainController {

@Autowired
private TestEntityRepository testEntityRepository;

@RequestMapping(value = "/main")
public String index() {
    return "/index.jsp";
}

@ResponseBody
@RequestMapping(value = "/index/{id}", method = RequestMethod.GET)
public List<TestEntity> getTestEntity(@PathVariable("id") Long id) {
    return testEntityRepository.findById(id);
}
}
