我正在使用入门指南学习Spring。现在我正在尝试完成“使用REST访问JPA数据”指南，但我的代码不起作用，所以我尝试了“完整”版本，但它也不起作用。到目前为止，每当我使用Spring Tool Suite（STS）导入内容时，根据指南中的描述，“完整”版本按预期执行，但现在不会发生。
指南指示我将项目作为“Spring Boot App”运行，然后执行curl命令以查看顶级服务：
命令：
$ curl http://localhost:8080
预期产出：
{
"_links" : {
"people" : {
"href" : "http://localhost:8080/people{?page,size,sort}",
"templated" : true
}
}
}
我的输出：
{"timestamp":1472183640477,"status":404,"error":"Not Found","message":"No message available","path":"/"}
我使用的是Windows 10 Pro x64，Java 1.8.0_102，STS版本3.8.1.RELEASE，内部版本号为201607290850并使用Spring Boot版本1.4.0.RELEASE。我正在使用Maven构建STS内部。
代码很简单，只有三个类，我没有改变任何东西。您可以查看代码here on github。春季指南是here。
这是我的控制台输出，我想我可能会遗漏一些重要信息，这有助于找出问题：

你可以看到有很多映射（所有 Mapped“{[/ {repository} / 行）都比你得到的还多。
如果我使用以下方法手动构建和运行项目，我会得到相同的结果：
mvn clean package
java -jar target\target\gs-accessing-data-rest-0.1.0.jar
STS是否显示它使用的命令？
答案 1 :(得分：0)
我从Maven执行了构建，这次它显示了一个jar文件已损坏的消息：
[WARNING] error reading C:\Users\Alisson\.m2\repository\org\springframework\data\spring-data-rest-webmvc\2.5.2.RELEASE\spring-data-rest-webmvc-2.5.2.RELEASE.jar; invalid LOC header (bad signature)
我删除了“spring-data-rest-webmvc”文件夹，下次运行构建时，Maven再次下载了正确的jar。现在它也可以从命令行和STS内部工作。
STS没有显示此错误消息，我尝试过“更新项目... /强制更新快照/版本”，所以我想最好的选择是始终使用Maven来构建而不是“Run as Spring Boot”应用程序”。
