实体
public class Department {
private String departmentId;
private String departmentName;
private String departmentRemark;
/**
*
* create a instance Department.
*/
public Department(){

}
public Department(String departmentId, String departmentName,
String departmentRemark) {
super();
this.departmentId = departmentId;
this.departmentName = departmentName;
this.departmentRemark = departmentRemark;
}
public String getDepartmentId() {
return departmentId;

public void setDepartmentId(String departmentId) {
this.departmentId = departmentId;

public void setDepartmentName(String departmentName) {
this.departmentName = departmentName;

楼主什么问题？

[行猿]

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.setDepartmentRemark(rs.getString("department_remark")); 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; }

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remark为什么没打印出来啊

[zxhcloth]

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。

[a_b_a_b_a_b_a_b]

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。

大哥。。哪可以这样输出 遍历list啊
