flex datagrid 分页例子
最近做个分页的，分页从数据库取数据，还蛮通用的，分享一下。
先上分页组件，Pagin.mxml

DAO层：TeacherDAO.java

实体层：Teacher.java
package com.ying.Exam.model; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.FetchType; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.ManyToOne; import javax.persistence.Table; import javax.persistence.UniqueConstraint; import org.springframework.stereotype.Component; /** * Teacher entity. @author MyEclipse Persistence Tools */ @Component("teacher") @Entity @Table(name = "Teacher", schema = "dbo", catalog = "ExamSystem", uniqueConstraints = @UniqueConstraint(columnNames = "TeacherID")) public class Teacher implements java.io.Serializable { // Fields private Integer id; private School school; //private StaffRoom staffRoom; private String teacherId; private String pwd; private String name; private String question; private String answer; private String title; // Constructors /** default constructor */ public Teacher() { } @Id @GeneratedValue @Column(name = "ID", unique = true, nullable = false) public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "SchoolID") public School getSchool() { return this.school; } public void setSchool(School school) { this.school = school; } // @ManyToOne(fetch = FetchType.EAGER) // @JoinColumn(name = "RoomID") // public StaffRoom getStaffRoom() { // return this.staffRoom; // } // // public void setStaffRoom(StaffRoom staffRoom) { // this.staffRoom = staffRoom; // } @Column(name = "TeacherID", unique = true, nullable = false, length = 20) public String getTeacherId() { return this.teacherId; } public void setTeacherId(String teacherId) { this.teacherId = teacherId; } @Column(name = "Pwd", nullable = false, length = 20) public String getPwd() { return this.pwd; } public void setPwd(String pwd) { this.pwd = pwd; } @Column(name = "Name", length = 20) public String getName() { return this.name; } public void setName(String name) { this.name = name; } @Column(name = "Question", length = 50) public String getQuestion() { return this.question; } public void setQuestion(String question) { this.question = question; } @Column(name = "Answer", length = 50) public String getAnswer() { return this.answer; } public void setAnswer(String answer) { this.answer = answer; } public void setTitle(String title) { this.title = title; } @Column(name = "Title", length = 20) public String getTitle() { return title; } }
School类 有ID和name属性就行了。
SchoolService、SchoolDAO就不贴了。和TeacherService，TeacherDAO差不多，改个名就行了。

修改dispatcherServlet-servlet.xml 中的 <prop key="hibernate.hbm2ddl.auto">update</prop>
改为<prop key="hibernate.hbm2ddl.auto">create</prop>
再修改连接属性，部署项目启动服务器会自动创建表。
再改回：<prop key="hibernate.hbm2ddl.auto">update</prop>
否则再次启动服务器时候又重建表，数据会丢失。测试数据时注意 教师编号不要重复，不然不能插入数据。
效果：姓名旁边有个Input， 可以根据输入动态查询。
