我是春天世界的新手。我一直在尝试使用Spring数据编写基本应用程序，使用Hibernate和MYSql数据库编写JPA。 我看到了错误： 没有为限定符'transactionManager'找到匹配的PlatformTransactionManager bean

这是我的spring-config.xml：

    <?xml version="1.0" encoding="UTF-8"?>

    <beans xmlns="http://www.springframework.org/schema/beans"

        <property name="jpaDialect" ref="jpaDialect" />
   </bean>

       <tx:annotation-driven transaction-manager="txManager" />

</beans>

这是我的Employee.java（myPOJO）：

@Entity
@Table(name = "employee")
public class Employee {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "employee_id")
private long employeeId;

@Column(name = "employee_name")
private String employeeName;

public Employee() {
}

public Employee(String employeeName) {
    this.employeeName = employeeName;
}

public long getEmployeeId() {
    return this.employeeId;
}

public void setEmployeeId(long employeeId) {
    this.employeeId = employeeId;
}

public String getEmployeeName() {
    return this.employeeName;
}

public void setEmployeeName(String employeeName) {
    this.employeeName = employeeName;
}
}

这是我的存储库：     公共接口EmployeeRepository扩展了JpaRepository     {         员工保存（员工员工）; 

    //@Query("select distinct employee_name from employee")
    //public Slice<String> findAllDistinctNames(Pageable pageable);
    public Slice<String> findAllByEmployeeName(Pageable pageable);
}

                    ApplicationContext context = new ClassPathXmlApplicationContext("spring-configuration.xml");
                    System.out.println("Context : " + context);
                    //Fetch the DAO from Spring Bean Factory
                    EmployeeRepository repository = (EmployeeRepository)context.getBean("employeeRepository");
                    Employee employee = new Employee("Employee123");
                    //employee.setEmployeeId("1");

                    //Save an employee Object using the configured Data source
                    repository.save(employee);
                    System.out.println("Employee Saved with EmployeeId "+employee.getEmployeeId());

                    //find an object using Primary Key
                    Employee emp = repository.findOne(employee.getEmployeeId());
                    System.out.println(emp);

                    //Close the ApplicationContext
                    ((ConfigurableApplicationContext)context).close();

            }
            catch (BeansException e)
            {
                    e.printStackTrace();
            }
    }

当我运行代码时，我正在低于堆栈跟踪：

任何想法，我在这里缺少哪一件。

1 个答案:

答案 0 :(得分：8)

可能是Spring想要事务管理器，默认名称是transactionManager。因此，尝试将txManager重命名为transactionManager。或者在需要的地方指定当前经理名称。
