我的dao为 sql
String sql="select inves from InvestmentProject inves ,in(inves.subModes) subMode,in(msg.districts) dist where 1=1";
if((Integer)map.get("target") == 1){
if (!map.get("keyword").equals("")) {
sql+=" and inves.keyword like '%"+map.get("keyword")+"%' ";
}
}else if ((Integer)map.get("target") == 2){
if (!map.get("keyword").equals("")) {
sql+=" and inves.name like '%"+map.get("name")+"%' ";
}
}
if((Integer)map.get("industry")>0){
sql+=" and theIndustry.id="+(Integer)map.get("industry")+" ";
}
if(map.get("district_ids")!=null){
Set<Integer> set = (Set<Integer>)map.get("district_ids");
int j=0;
String district_ids="";
for(Integer i:set){
if(j==0){
district_ids=i+"";
}else{
district_ids+= ","+i;
}
j++;
}
sql+=" and dist.id in("+district_ids+")";
}
if(map.get("modesS")!=null){
sql+=" and modes.id="+(Integer)map.get("modesS")+" ";
}
if(map.get("subMode_ids")!=null){
Set<Integer> set = (Set<Integer>)map.get("subMode_ids");
int z=0;
String subMode_ids="";
for(Integer i:set){
if(z==0){
subMode_ids=i+"";
}else{
subMode_ids+= ","+i;
}
z++;
}
sql+=" and subMode.id in("+ subMode_ids+")";
}
........
Query query = entityManager.createQuery(sql);
List<InvestmentProject> listIn=query.getResultList();
不在道是怎么回事
请教前辈名指点我是通过对象查询关联了很多表
谢谢你们帮帮忙
[解决办法]
缺少jar文件
加入antlr.jar
[解决办法]
那为啥找不到类呢？
难道你的jar里没那个文件？
打开你的jar看下吧，看看能不能找到antlr.RecognitionException
