Spring JDBC

通过Spring框架提供的模板功能，执行SQL。以下是相关代码

Application.java

package com.bf;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Application {

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

JDBCDAO printer = (JDBCDAO)context.getBean("dao");
SpitterObj spitter = printer.getSpitter(1038);
System.out.println(spitter.getLOT());
}
}

JDBCDAO.java

package com.bf;

import java.sql.ResultSet;
import java.sql.SQLException;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;

public class JDBCDAO implements SpitterDAO {
private static String GET_SQL = "select code_item from table where ID_NO = ?";

private JdbcTemplate jdbcTemplate;
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}

public SpitterObj getSpitter(int ljdm) {
return jdbcTemplate.queryForObject(GET_SQL, new RowMapper<SpitterObj>() {
public SpitterObj mapRow(ResultSet rs, int rowNum) throws SQLException {
SpitterObj obj = new SpitterObj();
obj.setLOT(rs.getString(1));
return obj;
}
}, ljdm);
}
}

SpitterDAO.java

package com.bf;

public interface SpitterDAO {
SpitterObj getSpitter(int ljdm);
}

SpitterObj.java

package com.bf;

public class SpitterObj {
private String ljdm;

public String getLOT() {
return ljdm;
}
public void setLOT(String ljdm) {
this.ljdm = ljdm;
}
}
