Answer 1

实现方法：
public ArrayList<Department> findAllDepartment() {
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;

ArrayList<Department> list =new ArrayList<Department>();

String sql="select * from asset_department order by department_id";
try {
conn=DB.getConn();
stmt=DB.getStatement(conn);
rs=DB.getResultSet(stmt, sql);
while(rs.next()){
Department department=new Department();
department.setDepartmentId(rs.getString("department_id"));
department.setDepartmentName(rs.getString("department_name"));
department.setDepartmentRe(rs.getString("department_re"));
list.add(department);
System.out.println(list);
}
} catch (SQLException e) {
e.printStackTrace();
}finally {
DB.closeRs(rs);
DB.closeStmt(stmt);
DB.closeConn(conn);
}
System.out.println("ListSize为："+list.size());
return list;
}

Answer 2

为什么打印出来的list是这个样子啊
也就是三个字段只打印出了一个departmentName，id和re为什么没打印出来啊

Answer 3

我晕，System.out.println(list);你直接打印List对象怎么可能会出你要的效果。
要么你重写List的toString()方法，要么你老老实实的遍历List，一个对象一个对象的打印。

Answer 4

输出list是会出现那种结果啊，您下面的那些什么什么部是怎么打出来的啊。

Answer 5

大哥。。哪可以这样输出 遍历list啊
