针对数据库操作,Spring框架提供了JdbcTemplate类。
1.Spring JDBC的配置
创建配置文件applicationContext.xml,添加如下代码:
1 <!--配置数据源--> 2 <bean 3 class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 4 <property name="driverClassName" value="com.mysql.jdbc.Driver"/> 5 <property name="url" value="jdbc:mysql://localhost:3306/springjdbc"/> 6 <property name="username" value="root"/> 7 <property name="password" value="root"/> 8 </bean> 9 <!--配置JDBC模板--> 10 <bean > 11 <property name="dataSource" ref="dataSource"/> 12 </bean> 13 <!--配置注入类--> 14 <bean > 15 <property name="jdbcTemplate" ref="jdbcTemplate"/> 16 </bean>
2.创建Javabean和Dao接口
1 public class User { 2 private Integer id; 3 private String name; 4 private Integer age; 5 6 public Integer getId() { return id; } 7 8 public void setId(Integer id) { 9 this.id = id; 10 } 11 12 public String getName() { 13 return name; 14 } 15 16 public void setName(String password) { 17 this.name = password; 18 } 19 20 public Integer getAge() { return age; } 21 22 public void setAge(Integer age) { 23 this.age = age; 24 } 25 }
