添加 jpa 依赖项后 Spring Boot 构建错误答案

【问题标题】：Spring boot build error after adding jpa depencency添加 jpa 依赖项后 Spring Boot 构建错误
【发布时间】：2017-05-29 22:49:05
【问题描述】：

我正在使用父依赖作为

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.3.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

使用 JPA 依赖项我收到以下错误：

ationConfigEmbeddedWebApplicationContext : 遇到异常在上下文初始化期间 - 取消刷新尝试： org.springframework.beans.factory.UnsatisfiedDependencyException：在类路径中定义名称为“dataSource”的 bean 创建错误资源 [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]：通过方法“dataSource”参数表示的不满足的依赖关系 0;嵌套异常是 org.springframework.beans.factory.BeanCreationException：错误用名字创建bean 'spring.datasource-org.springframework.boot.autoconfigure.jdbc.DataSourceProperties'： bean 实例化失败；嵌套异常是 org.springframework.beans.BeanInstantiationException：失败实例化 [org.springframework.boot.autoconfigure.jdbc.DataSourceProperties]：构造函数抛出异常；嵌套异常是 java.lang.NoClassDefFoundError： org/springframework/dao/DataAccessException

删除项目从 pom.xml 编译的项目构建的 spring-boot-starter-data-jpa 依赖项后，错误消失。

该项目一直运行到今天，但在 Java 更新后我收到此错误。

更新：我在应用程序中只有一个 hello restcontroller，它返回简单的字符串

【问题讨论】：

分享 pom.xml
您是否使用数据源自动配置？ .可以分享一下数据源配置吗？
我没有使用任何数据源，我只是添加了 jpa 依赖项并运行....并出现错误....这是一些疯狂的事情
您有 derby db 运行时，请将其注释掉（如果您不使用）。还排除自动配置，如 @SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
嗨 Barath，我将在内存中使用 Derby db，因此，我知道 jpa 将自动配置为 derby db。

标签： maven spring-boot spring-data-jpa

【解决方案1】：

当你添加 spring-boot-starter-data-jpa 时，Spring Boot 会查找数据源属性，以便它可以连接到数据库。

您需要将以下属性添加到 application.properties（根据您机器上的 DB 配置更改值）

spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

如果您想测试（或使用）spring-data-jpa，请在您的 pom.xml 中使用以下内存数据库依赖项。在这种情况下，您不需要添加任何属性，Spring Boot 会为您自动配置。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <scope>runtime</scope>
</dependency>

【讨论】：

感谢您的回复，按照您的步骤我仍然有问题，这似乎是我无法得到的不同问题。我更喜欢添加内存数据库，这是调试错误 ========================= 自动配置报告 ======== ================= 正匹配： ----------------- AopAutoConfiguration 匹配： - @ConditionalOnClass 找到所需的类 'org.springframework .context.annotation.EnableAspectJAutoProxy', 'org.aspectj.lang.annotation.Aspect', 'org.aspectj.lang.reflect.Advice' (OnClassCondition) ....
你能分享整个错误堆栈吗..上面的评论没有错误的根本原因
我已经用详细信息更新了问题，一旦我添加了 jpa 依赖项，我就会遇到问题。

【解决方案2】：

我解决了这个问题。我从 .m2 文件夹中删除了所有存储库（c:/users/{USER}/.m2/repository）然后重建工作区......它可以工作
