大家好,即使我从他们的网站上关注了春季教程,我仍然会收到此错误.我一直试图弄清楚为什么我会收到这个错误.我可以连接到Facebook但是当试图检索像春天提供的教程这样的提要时,我不断收到白标错误.它说:
此应用程序没有/ error的显式映射,因此您将此视为回退.出现意外错误(type = Not Found,status = 404).没有可用的消息
一切似乎都没问题,但不知道为什么我一直收到这个错误.如果有人可以提供帮助我会很感激.
我的控制器放在src/main/java/home中:
@Controller
@RequestMapping(value="/")
public class HomeController {
private Facebook facebook;
@Inject
public HomeController(Facebook facebook) {
this.facebook = facebook;
}
@RequestMapping( method =RequestMethod.GET)
public String getPhotos(Model model){
if(!facebook.isAuthorized())
{
return "redirect:/connect/facebook";
}
model.addAttribute(facebook.userOperations().getUserProfile());
PagedList<Post> homeFeed = facebook.feedOperations().getHomeFeed();
model.addAttribute("feed", homeFeed);
return "hello";
}
}
Application.java文件放在src/main/java/home/main中:
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
下面是我的build.gradle文件:
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'spring-boot'
buildscript{
repositories{
// maven { url "https://repo.spring.io/release" }
maven { url "https://repo.spring.io/libs-milestone"}
// mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.3.RELEASE")
}
}
repositories {
maven { url "https://repo.spring.io/libs-milestone"}
mavenCentral()
}
bootRepackage {
mainClass = 'facebookArchiver.Application'
}
dependencies {
compile ('org.springframework.social:spring-social-facebook:2.0.0.RELEASE')
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
compile('org.springframework.boot:spring-boot-starter-web')
testCompile group: 'junit', name: 'junit', version: '4.11'
}
task wrapper(type: Wrapper) {
gradleVersion = '2.3'
}
hello.html文件:它保存在src/main/resources/templates文件夹中:
<html>
<head>
<title>Hello Facebook</title>
</head>
<body>
<h3>Hello, <span th:text="${facebookProfile.name}">Some User</span>!</h3>
<h4>Here is your home feed:</h4>
<div th:each="post:${feed}">
<b th:text="${post.from.name}">from</b> wrote:
<p th:text="${post.message}">message text</p>
<img th:if="${post.picture}" th:src="${post.picture}"/>
<hr/>
</div>
</body>
</html>
facebookConnect.html:它存储在src/main/resources/templates/connect文件夹下:
<html>
<head>
<title>Hello Facebook</title>
</head>
<body>
<h3>Connect to Facebook</h3>
<form action="/connect/facebook" method="POST">
<input type="hidden" name="scope" value="read_stream" />
<div class="formInfo">
<p>You aren't connected to Facebook yet. Click the button to connect this application with your Facebook account.</p>
</div>
<p><button type="submit">Connect to Facebook</button></p>
</form>
</body>
</html>
最后facebookConnected.html:还存储在src/main/resources/templates/connect文件夹下:以下是facebookConnected.html的文件:
<html>
<head>
<title>Hello Facebook</title>
</head>
<body>
<h3>Connected to Facebook</h3>
<p>
You are now connected to your Facebook account.
Click <a href="/">here</a> to see some entries from your Facebook photos.
</p>
</body>
</html>

如果您的控制器采用不同的包结构,则@ComponentScan需要将其添加到Spring Boot应用程序中class.
示例:
@ComponentScan(basePackages={"package name of where the controller is"})
