User Instances JdbcTemplate in spring

1, first configure the JdbcTemplate

Configure a JdbcTemplate bean in the Spring IOC container, inject DataSource (using a third-party data source c3p0), and inject jdbctemplate into the custom DAO.

<bean id="DS"class="Com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="User"Value="Root"/> <property name="Password"Value="Root"/> <property name="Jdbcurl"Value="jdbc:mysql:///db_test"/> <property name="Driverclass"Value="Com.mysql.jdbc.Driver"/></bean><bean id="JdbcTemplate"class="org.springframework.jdbc.core.JdbcTemplate"> <property name="DataSource"ref="DS"/></bean>

2, in the custom DAO class is configured as follows, for private jdbctemplate temp; Add annotations to allow the framework to inject the object automatically. DAO layer classes using @Repository annotations

@Repositorypublic class Userdaoimpl implements Userdao {@Autowired private jdbctemplate temp; @Override public boolean Add (user user) {String SQL="INSERT into user values (?,?,?,?)"; int update=temp.update (SQL, User.getid (), User.getname (), User.getage (), user.getaddress ()); returnUpdate >0?true:false; } @Override public boolean update (user user) {String SQL="Update user set name=?, age=?, address=? where id=?"; int update=temp.update (SQL, User.getname (), User.getage (), user.getaddress (), User.getid ()); returnUpdate >0?true:false; }
}

3. Testing

Public class Jdbctest {private UserService service; @Before public void before () {Classpathxmlapplicationcontext CTX= New Classpathxmlapplicationcontext ("Beans.xml"); Service=Ctx.getbean (Userserviceimpl.class); } @Test public void Add () {User User=new User (); User.setname ("Guo Jing"); User.setage ( at); User.setaddress ("Beijing");    Service.add (user); } @Test public void Update () {User User=new User (); User.setid (1); User.setname ("Huang Rong"); User.setage ( -); User.setaddress ("Nanchang");    Service.update (user); }
}
