批量插入。AJAX发起请求,核心代码如下:
var mids = new Array();
for (var i=0; i< rows.length; i++) {
mids.push(rows[i].id);
}
$.ajax({
type: ‘POST’,
dataType: “json”,
async: false,
traditional:true, //这一行很重要
url: parent.getBasePath()+“sys/role/setAuth.do”,
data: {‘mids’: mids},
success: function(data) {},
error: function(err) {}
});
接下来是Controller的代码:
//直接在方法里传入List会报错,所以要通过一个类封装一层
@RequestMapping("/setAuth")
@ResponseBody
public Map<String,Object> setAuth(Short id, ModParam midsA) {
}
//封装List对象的类
public class ModParam implements Serializable{
private static final long serialVersionUID = 8607859409880232081L;
private List<Short> mids;
public List<Short> getMids() {
return mids;
}
public void setMids(List<Short> mids) {
this.mids = mids;
}
}
Contoller一层一层的往下调用,最后到了Mapper:
/***
- 批量插入
- @return
- @throws Exception
*/
int insertWithList(List<RoleResource> rr) throws Exception;
对应的xml(我这里的id不是一个自增的Sequence,我是去表中选取最大的id,然后依次加1,写入到对象,所以没有用到mybatis的selectKey,这里是针对Oracle):
<insert id=“insertWithList” parameterType=“java.util.List”>
insert into T_WEB_ROLE_RESOURCE(id, role_id, source_id, remark)
<foreach collection=“list” item=“item” index=“index” separator=“union all”>
select #{item.id},#{item.roleId},#{item.sourceId},#{item.remark} from dual
</foreach>
</insert>
嗯,这就差不多了。
