报这样的错用ext写的从数据库读取数据
action
List<Employeeinfo> elist;
RoleInfoBiz roleInfoBiz;
String json;
Employeeinfo employeeinfo;
public String allEmployeeinfo() {
elist=roleInfoBiz.allEmp();
String result="[";
for (int i=0;i<elist.size();i++) {
result+="{employeeId:"+elist.get(i).getEmployeeId()+"',employeeName:'"+elist.get(i).getEmployeeName()+"',gender'"+elist.get(i).getGender()+"',tbUser:'"+elist.get(i).getTbUser().getRole().getRoleName()+"',departinfo:'"+elist.get(i).getDepartinfo().getDepartName()+
"',phone:'"+elist.get(i).getPhone()+"',qq:'"+elist.get(i).getQq()+"',email:'"+elist.get(i).getEmail()+"',address:'"+elist.get(i).getAddress()+"}";
if (i!=elist.size()-1){
result+=",";
}
}
result+="]";
json="{\"success\":true,\"elist\":"+result+"}";
System.out.println(json);
return SUCCESS;
}
public List<Employeeinfo> getElist() {
return elist;
}
public void setElist(List<Employeeinfo> elist) {
this.elist = elist;

很急谢谢各位
[解决办法]
应该是json字符串拼接错了，建议用JSONArray.fromObject(list).toString()这个函数，网上搜一下用法把，要导入几个jar包。
