JpaRepository won't save data - spring

Question

I use JpaRepository to save data, but the hibernate.show_sql shows "select" and won't save data. Following is my service:
#Autowired
private UserRepository userRepository;
#PostConstruct
public void init() {
User admin = new User();
admin.setDisplayName("admin");
admin.setEmailAddress("admin#admin");
admin.setPassword("admin___");
admin.setRegisteredAt(new Date());
admin.setLastAccessAt(new Date());
admin.setUuid(UUID.randomUUID().toString());
try {
System.out.println("before save");
userRepository.save(admin);
System.out.println("after save");
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
The output looks like this:
========before save======
Hibernate: select user0_.uuid as uuid1_0_0_, user0_.display_name as display_2_0_0_, user0_.email_address as email_ad3_0_0_, user0_.last_access_at as last_acc4_0_0_, user0_.password as password5_0_0_, user0_.registered_at as register6_0_0_ from User user0_ where user0_.uuid=?
========after save=======
Following is my applicationContext.xml:
<context:component-scan base-package="test">
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/helloworld" />
<property name="username" value="root" />
<property name="password" value="password" />
</bean>
<bean id="myEmf"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="packagesToScan" value="test.entity"></property>
<property name="dataSource" ref="myDataSource" />
<property name="jpaProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="persistenceProvider">
<bean class="org.hibernate.jpa.HibernatePersistenceProvider"></bean>
</property>
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="myDataSource" />
</bean>
<jpa:repositories base-package="test.repository"
entity-manager-factory-ref="myEmf" transaction-manager-ref="transactionManager"></jpa:repositories>
Attached is my class generated by JPA Tools:
#Entity
#NamedQuery(name="User.findAll", query="SELECT u FROM User u")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private String uuid;
#Column(name="display_name")
private String displayName;
#Column(name="email_address")
private String emailAddress;
#Temporal(TemporalType.TIMESTAMP)
#Column(name="last_access_at")
private Date lastAccessAt;
private String password;
#Temporal(TemporalType.TIMESTAMP)
#Column(name="registered_at")
private Date registeredAt;
public User() {
}
public String getUuid() {
return this.uuid;
}
public void setUuid(String uuid) {
this.uuid = uuid;
}
public String getDisplayName() {
return this.displayName;
}
public void setDisplayName(String displayName) {
this.displayName = displayName;
}
public String getEmailAddress() {
return this.emailAddress;
}
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
public Date getLastAccessAt() {
return this.lastAccessAt;
}
public void setLastAccessAt(Date lastAccessAt) {
this.lastAccessAt = lastAccessAt;
}
public String getPassword() {
return this.password;
}
public void setPassword(String password) {
this.password = password;
}
public Date getRegisteredAt() {
return this.registeredAt;
}
public void setRegisteredAt(Date registeredAt) {
this.registeredAt = registeredAt;
}
}

Since you're using JPA, the transaction manager should be a JpaTransactionManager, not a DataSourceTransactionManager.
