我使用的是Spring-boot，因此在Tomcat 7中部署了战争。启动应用程序时，我得到以下信息：

这是我的应用程序启动的方式：

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

当我的Spring控制器处理连接时：

@Controller
public class GetController {

    private UserService userService;

    @Autowired 
    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {
        User user = null;

        user = userService.getUser(id);

        return user;
    }
}

它在userService上执行getUser：

@Component
public class UserService {

    private UserDAO UserDao;

    public UserDAO getUserDao() {
        return UserDao;
    }

    @Autowired
    public void setUserDao(UserDAO UserDao) {
        this.UserDao = UserDao;
    }

    public User getUser(int id) {
        return getUserDao().load(id);
    }
}

使用userDao查找实体：

@Repository("userDao")
@Transactional(propagation=Propagation.REQUIRED)
public class UserDAO {

    @PersistenceContext
    private EntityManager entityManager;

    public void insert(User user) {
        entityManager.persist(user);
    }

    public User load(int id) {
        return entityManager.find(User.class, id);
    }
}

我在/ src / main / resources中具有以下spring-config.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

        <property name="persistenceUnitName" value="userPersistenceUnit" />
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
        <property name="jpaDialect" ref="jpaDialect" />
    </bean>

    <bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
        <property name="database" value="HSQL" />
        <property name="databasePlatform" value="org.hibernate.dialect.HSQLDialect" />
    </bean>

    <bean id="jpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
        <property name="dataSource" ref="dataSource" />
        <property name="jpaDialect" ref="jpaDialect" />
    </bean>

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

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.postgresql.Driver" />
        <property name="url" value="jdbc:postgresql://localhost:5432/mydb" />
        <property name="username" value="my_user" />
        <property name="password" value="" />
    </bean>
</beans>

最后但并非最不重要的是以下/src/main/resources/persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    version="1.0">
    <persistence-unit name="userPersistenceUnit" transaction-type="RESOURCE_LOCAL" >
    <class>com.mydomain.orm.User</class>
</persistence-unit>
</persistence>

我需要怎么做才能解决此错误？
