--------------------编程问答-------------------- 这个貌似不是因为批量删除引起的。
可能是由于Action方法调用出的错，你把你的action代码贴出来看一下。 --------------------编程问答-------------------- 测试可以通过。。。
package com.lzh.action;
import com.lzh.service.ILinkService;
import com.opensymphony.xwork2.ActionSupport;
public class LinkDelAll extends ActionSupport{
private ILinkService iLinkService;
private Integer[] lid;
public ILinkService getiLinkService() {
return iLinkService;
}
public void setiLinkService(ILinkService iLinkService) {
this.iLinkService = iLinkService;
}
public Integer[] getLid() {
return lid;
}
public void setLid(Integer[] lid) {
this.lid = lid;
}
@Override
public String execute() throws Exception {
System.out.println("id="+lid);
for(int j:lid){
System.out.println("id="+j);
}
iLinkService.delAll(lid);
return SUCCESS;
}
}
--------------------编程问答-------------------- 这是dao层的方法
public int delAll(final Integer[] lid) {
return (Integer) this.getHibernateTemplate().execute(
new HibernateCallback() {
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
try {
String sql = "delete Link where lid in (:ids)";
Query query = getSession().createQuery(sql);
query.setParameterList("ids", lid);
// query.setParameter("ids", id);
query.executeUpdate();
} catch (Exception re) {
re.printStackTrace();
}
System.out.println("--------------");
return 1;
}
});
} --------------------编程问答-------------------- 这是我写的测试类
package com.lzh.service.impl;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import com.lzh.model.Link;
import com.lzh.service.ILinkService;
import com.lzh.service.IUserService;
import com.opensymphony.xwork2.interceptor.annotations.Before;
import junit.framework.TestCase;
public class TestLink extends TestCase {
ILinkService service;
//IUserService userService;
@Before
public void setUp() throws Exception
{
ApplicationContext context = new FileSystemXmlApplicationContext("E:\\Jean\\Workspaces\\MyEclipse 8.5\\struts_spring_hibernate01\\WebRoot\\WEB-INF\\applicationContext.xml");
service = (ILinkService) context.getBean("LinkService");
//userService=(IUserService)context.getBean("UserService");
}
// public void testFindLinkById()
// {
// String yszmc = service.findById(1).getLname();
// System.out.println(yszmc);
//
// }
// public void testSaveLink(){
// Link link=new Link(222,"fasdf","dafd","dadsf");
// service.save(link);
// }
public void testDelAll(){
Integer[] i={7,8,9};
System.out.println("i="+i);
//service.delAll(i);
}
}
--------------------编程问答-------------------- 既然dao层测试通过，那就说明action配置的有问题。
你好好分析下action配置哪里出问题了。 --------------------编程问答-------------------- in (:ids)";这里错了
补充：Java , Web 开发
