这边文章是接的刚刚前一遍的基础上敲的 SSH框架的多表查询和增删查改 (方法一)上

  SSH框架的多表查询和增删查改 (方法一)中

一:

现在配置你的 applicationContext.xml , web.xml 配置文件

1):applicationContext.xml  --》这些配置你大概大概理解就好不要敲啊,反正我是复制的这些配置

这篇文章讲解了Spring 开启Annotation <context:annotation-config> 和 <context:component-scan>诠释及区别

</beans>

2):web.xml  --》这些配置你大概大概理解就好不要敲啊,反正我是复制的这些配置

</filter-mapping>
</web-app>

二:创建这些package的包(按你个人习惯)

SSH框架的多表查询和增删查改 (方法一)中

1):先去po包下  新建实体类

创建实体之前说说一对多的情况

多表查询

1:员工和部门表 :1对多 ==》1是部门   多是员工
因为一个员工只能属于一个部门 而一部们则是可以有多个员工 2: 在po层的设置 部门表:就要设置 Set的属性来包含 员工
看: private Set<TbEmp> setEmps = new HashSet<TbEmp>(); public Set<TbEmp> getSetEmps() {
return setEmps;
} public void setSetEmps(Set<TbEmp> setEmps) {
this.setEmps = setEmps;
} 而在 员工表的设置:就要设置 部门 private TbDept tbDept;
public TbDept getTbDept() {
return tbDept;
}
public void setTbDept(TbDept tbDept) {
this.tbDept = tbDept;
} 3: 然后在去 cfg的文件夹下 TbDept.hbm.xml(部门)==》 class==>包含的是员工的全路径哦,不是它自己的全路径,
name==>setEmps这个名称是你刚刚在 po层中部门设置 包含员工的名称
column="did"===》did===》是员工的外键哦 并且员工TbEmp.hbm.xml 的 column="did" 也要设置 did哦 反正名称必须相同 <set name="setEmps" cascade="save-update" inverse="true">
<key column="did"></key>
<one-to-many class="zhu.po.TbEmp"/>
</set> TbEmp.hbm.xml 员工 <many-to-one name="tbDept" class="zhu.po.TbDept" column="did" insert="false" update="false">
</many-to-one>

1:创建TbDept.java(部门表)的实体类

SSH框架的多表查询和增删查改 (方法一)中

package zhu.po;

import java.util.HashSet;
import java.util.Set; //部门表
public class TbDept {
private Integer did;
private String dname; //部门包含员工
private Set<TbEmp> setEmps = new HashSet<TbEmp>(); public Set<TbEmp> getSetEmps() {
return setEmps;
} public void setSetEmps(Set<TbEmp> setEmps) {
this.setEmps = setEmps;
} public Integer getDid() {
return did;
} public void setDid(Integer did) {
this.did = did;
} public String getDname() {
return dname;
} public void setDname(String dname) {
this.dname = dname;
} }

创建TbEmp.java(员工表)的实体类

package zhu.po;

import java.util.Date;
//员工表
public class TbEmp {
private Integer eid;
private String ename;
private int did;
private String gende;
private int age;
private Date workDate;
private String password; //部门
private TbDept tbDept; public Integer getEid() {
return eid;
}
public void setEid(Integer eid) {
this.eid = eid;
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
} public int getDid() {
return did;
}
public void setDid(int did) {
this.did = did;
}
public String getGende() {
return gende;
}
public void setGende(String gende) {
this.gende = gende;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Date getWorkDate() {
return workDate;
}
public void setWorkDate(Date workDate) {
this.workDate = workDate;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public TbDept getTbDept() {
return tbDept;
}
public void setTbDept(TbDept tbDept) {
this.tbDept = tbDept;
} }

2:cfg包

创建实体类的映射文件

SSH框架的多表查询和增删查改 (方法一)中

SSH框架的多表查询和增删查改 (方法一)中

创建TbDept.hbm.xml

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
<class name="zhu.po.TbDept" table="tbdept" catalog="jdbc01">
<id name="did" type="java.lang.Integer">
<column name="did" />
<generator class="identity" />
</id>
<property name="dname" type="java.lang.String">
<column name="dname" length="8" />
</property>
<!--
TbDept.hbm.xml(部门)==》 class==>包含的是员工的全路径哦,不是它自己的全路径,
name==>setEmps这个名称是你刚刚在 po层中部门设置 包含员工的名称
column="did"===》did===》是员工的外键哦 。
并且员工TbEmp.hbm.xml 的
column="did" 也要设置 did哦 反正名称必须相同
-->
<set name="setEmps" cascade="save-update" inverse="true">
<key column="did"></key>
<one-to-many class="zhu.po.TbEmp"/>
</set> </class>
</hibernate-mapping>

创建TbEmp.hbm.xml (与上面的同理)

<many-to-one name="tbDept" class="zhu.po.TbDept" column="did" insert="false" update="false">
</many-to-one>

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
<class name="zhu.po.TbEmp" table="tbemp" catalog="jdbc01">
<id name="eid" type="java.lang.Integer">
<column name="eid" />
<generator class="identity" />
</id>
<property name="did" type="java.lang.Integer">
<column name="did" length="12" />
</property>
<property name="ename" type="java.lang.String">
<column name="ename" length="12" />
</property>
<property name="age" type="java.lang.Integer">
<column name="age" />
</property>
<property name="gende" type="java.lang.String">
<column name="gende" />
</property>
<property name="workDate" type="java.util.Date">
<column name="workDate" length="19" />
</property>
<property name="password" type="java.lang.String">
<column name="password" length="19" />
</property> <many-to-one name="tbDept" class="zhu.po.TbDept" column="did" insert="false" update="false">
</many-to-one> </class>
</hibernate-mapping>

然后在 applicationContext.xml  中配置映射  TbDept.hbm.xml 和TbEmp.hbm.xml

public boolean delete(int id) {

return EmpDao.findDataById(id);
} }

 action包

SSH框架的多表查询和增删查改 (方法一)中

之前的JDBC,我们使用jsp和servlet搭配,实现展现时,大体的过程是:

  1 jsp触发action

  2 servlet接受action,交给后台class处理

  3 后台class跳转到其他的jsp,实现数据展现

  现在使用struts2,实现过程变为

  1 jsp出发action

  2 struts2拦截请求,调用后台action

  3 action返回结果,由不同的jsp展现数据

当login.jsp触发action时,就会向后抬发送EmpAction.action的请求,这个请求被后台拦截,交给struts.xml中配置的action处理
