Exception in thread "main" java.lang.NullPointerException

at com.lrq.test.TestEmployee.main(TestEmployee.java:27)

原因主要是hql語句之間缺少空格引起了不合法異常

 String hql="select e from Employee e where e.empId>-1";
/*動態查詢*/
int count=0;
    if(employee.getEmpName()!=null&&!employee.getEmpName().equals("")){
        hql+="and e.empName=:eName";
count+=1;
}
    if(employee.getEmpPwd()!=null&&!employee.getEmpPwd().equals(""
 
)){
        hql+="and e.empPwd=:ePwd";
count+=2;
}

只要在 and 前面新增空格即可
