无法解析DataAccessException。它是从所需的.class文件间接引用的

I'm usign Spring ORM with Hibernate, and when I write the command

我使用Hibernate使用Spring ORM,当我编写命令时

hibernateTemplate.save(entityInstance);

(entityInstance is obviously an instance of a User entity)

(entityInstance显然是User实体的一个实例)

I get this error:

我收到此错误:

The type org.springframework.dao.DataAccessException cannot be resolved. It is indirectly referenced from required .class files

Even though i followed a (working) tutorial step-by-step (and code-by-code) it doesn't work. This is my pom.xml

即使我一步一步地遵循(工作)教程(并且逐个代码),它也不起作用。这是我的pom.xml

Eclipse also suggests me as 'quick fix' to configure build path from the menu, but I don't know exactly what to do. As some people suggested for similar issues here on SO, I tried by removing and reloading both JRE System Library and Maven dependencies, but didn't work.

Eclipse还建议我从菜单中“快速修复”配置构建路径,但我不确切知道该怎么做。正如有些人在SO上建议类似的问题一样,我尝试删除并重新加载JRE系统库和Maven依赖项,但是没有用。

3 个解决方案

#1

Download jar from this link

从此链接下载jar

import into your project, it will resolve.

导入到您的项目中,它将解决。

Your HibernateTemplate class is importing org.springframework.dao.DataAccessException class which is not present in your classpath.

#2

Add in pom for Maven project

为Maven项目添加pom

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>

or add jar spring-tx

或者添加jar spring-tx
