接口：
public interface StuDao {
public void insert();
public void delete();
}
public interface StuSer {
public void update();
}
实现：
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.support.JdbcDaoSupport;
import com.test.spring.interf.StuDao;
public class DaoImpl extends JdbcDaoSupport implements StuDao {
public void delete() {
JdbcTemplate jt= this.getJdbcTemplate();
String sql1 = "delete from student1 where id=1";
jt.update(sql1);
}
public void insert() {
JdbcTemplate jt= this.getJdbcTemplate();
String sql = "insert into student2 values (1,'jack','dd')";//这句话会出错
jt.update(sql);
}
}
public class StuSerImpl {
private DaoImpl dao;
public void update() {
try{
this.dao.delete();
this.dao.insert();
}catch(Exception e){
System.out.println("stuSerImpl-----"+e);
}
}
public DaoImpl getDao() {
return dao;
}
public void setDao(DaoImpl dao) {
this.dao = dao;
}
}
action：
public void setStuSerImpl(StuSerImpl stuSerImpl) {
this.stuSerImpl = stuSerImpl;
}
public StuSerImpl getStuSerImpl() {
return this.stuSerImpl;
}
private StuSerImpl stuSerImpl;
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
DForm dForm = (DForm) form; // TODO Auto-generated method stub
try{
stuSerImpl.update();
}catch(Exception e){
System.out.println("-------------"+e);
}
return null;
}
}

PROPAGATION_REQUIRED
[b]问题补充：[/b]
上面的写错了，是这样：
PROPAGATION_REQUIRED,-BadSqlGrammarException
[b]问题补充：[/b]
不做异常处理也不行啊。
