在Spring Boot应用程序中从Angular JS调用Rest Services时出错

Question

Spring Boot应用程序在后端托管REST服务，在前端托管Angular。 我正在从UI调用REST。

我的密码

$http.get(urls.USER_SERVICE_API)
                .then(
                    function (response) {
                        console.log('Fetched successfully all users');
                        $localStorage.users = response.data;
                        deferred.resolve(response);
                    },
                    function (errResponse) {
                        console.error('Error while loading users');
                        deferred.reject(errResponse);
                    }
                );


app.constant('urls', {
BASE: '<a class="vglnk" href="http://localhost:8081/SpringBootCRUDApp" rel="nofollow"><span>http</span><span>://</span><span>localhost</span><span>:</span><span>8081</span><span>/</span><span>SpringBootCRUDApp</span></a>',
USER_SERVICE_API : '<a class="vglnk" href="http://localhost:8081/SpringBootCRUDApp/api/user/" rel="nofollow"><span>http</span><span>://</span><span>localhost</span><span>:</span><span>8081</span><span>/</span><span>SpringBootCRUDApp</span><span>/</span><span>api</span><span>/</span><span>user</span><span>/</span></a>'
});

Google chrome浏览器中的错误调试如下所示：

angular.min.js:103 GET http://localhost:8081/SpringBootCRUDApp/%3Ca%20class=%22vglnk%22%20href=%22http://localhost:8080/SpringBootCRUDApp/api/user/%22%20rel=%22nofollow%22%3E%3Cspan%3Ehttp%3C/span%3E%3Cspan%3E://%3C/span%3E%3Cspan%3Elocalhost%3C/span%3E%3Cspan%3E:%3C/span%3E%3Cspan%3E8080%3C/span%3E%3Cspan%3E/%3C/span%3E%3Cspan%3ESpringBootCRUDApp%3C/span%3E%3Cspan%3E/%3C/span%3E%3Cspan%3Eapi%3C/span%3E%3Cspan%3E/%3C/span%3E%3Cspan%3Euser%3C/span%3E%3Cspan%3E/%3C/span%3E%3C/a%3E 404

从POSTMAN调用REST时，它是成功的。 因此，从UI调用时存在问题。 请帮助我找出我在UI其余调用部分中做错的事情。

Complete REST URL is ::

http://localhost:8081/SpringBootCRUDApp/api/user/

请帮忙 ！

您的app.constants中有错误的URL。 将其替换为REST URL应该会为您提供所需的结果。

USER_SERVICE_API: ' http://localhost:8081/SpringBootCRUDApp/api/user '

您当前指定的URL中包含许多未知标签。
