与Jpa的Spring STS DB连接

Question

我正在研究Spring STS，并尝试将DB与JPA连接。

我不熟悉Spring，所以在连接数据库时遇到问题。

如果我添加pom.xml此代码

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    <version>1.3.2.RELEASE</version>
</dependency>

我得到这个错误

HTTP Status 500 - Servlet.init() for servlet appServlet threw exception

type Exception report

message Servlet.init() for servlet appServlet threw exception

description The server encountered an internal error that prevented it from fulfilling this request.

尝试将spring-beans添加到您的pom.xml

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>4.2.4.RELEASE</version>
</dependency>
