Spring 学习日记 (四) Spring 整合Mybaits 和 struts2 框架的配置文件

其实也是挺无奈的  这东西永远这一棒子那一锤子的  太不系统了 哎 没办法 跟着项目走吧

首先准备的JAR包



需要配置的几个配置文件  

配置spring

applicationContext.xml  

配置mybaits

mybatis-config.xml

配置Struts2

struts.xml 

配置web

web.xml

配置映射文件

xxxxxxMapper.xml 

这些清楚了  就来看每个配置文件具体的设置

-------------------------------我是无耻的分割线 啦啦啦啦啦啦啦啦啦--------------------------

这里需要提一下spring xml文件注入的两种标签


constructor-arg：通过构造函数注入


property：通过setxx方法注入


分类说明是这么一个样子

constructor-arg：通过构造函数注入

</pre><pre name="code" class="html"><pre name="code" class="java">    public class Man {

private String name ;
private int age;
private List hobby;
private Map  friends;
private Set  set;
private boolean ifMarried;

public Man() {

}

public Man(String name, int age,List hobby,Map friends,Set    set,boolean ifMarried){
this.name = name;
this.age = age;
this.hobby = hobby;
this.friends = friends;
this.set = set;
this.ifMarried = ifMarried;
}

public String getInfo(){

String info = "姓名："+this.name+"\n年龄:"+this.age+"\n爱好:"+this.hobby+"\n朋友:"+this.friends+"\n婚否:"+this.ifMarried+"\n其他的："+this.set;
return info;
}

}

对应上面的java类 在xml这样配置

</pre><pre name="code" class="html"><pre name="code" class="html">	<bean id="man" class="com.spring.test.man.Man">
<constructor-arg value="zzy" index="0" >
</constructor-arg>

<constructor-arg value="10" index="1">
</constructor-arg>

<constructor-arg>
<list>
<value>movie</value>
<value>music</value>
</list>
</constructor-arg>

<constructor-arg>
<set>
<value>Lady is GaGa</value>
<value>GaGa is Lady</value>
</set>
</constructor-arg>

<constructor-arg>
<map>
<entry key="liuhua" value="man"></entry>
<entry key="xujinglei" value="female"></entry>
</map>
</constructor-arg>

<constructor-arg index="5" value="0">
</constructor-arg>
</bean>

同时这样还有其他的写法 比如写一个类 有下列参数

private String name;

private String tel;

private Dept dept;//注意 这里的是另外一个类Dept 所以会在xml中ref 而不是value 切记 切记

private String password;

Dept类

private String dname;

private String deptno;

那么注入会有下列的形式

第一种方法：根据索引赋值，索引都是以0开头的

<constructor-arg index="0" value="zhangsan" />
<constructor-arg index="1" value="10086" />
<constructor-arg index="2" ref="dept"/>
<constructor-arg index="3" value="男" />

第二种方法是根据所属类型传值 这种方法要注意取到的值得顺序

<constructor-arg type="java.lang.String" value="张三"
<constructor-arg type="java.lang.Double" value="10086" />
<constructor-arg type="www.ccav.Dept" ref="dept"/>
<constructor-arg type="java.lang.String" value="男" />

第三种方法：根据参数的名字传值：（推荐用法）

<constructor-arg name="name" value="张三" />
<constructor-arg name="tel" value="10086" />
<constructor-arg name="dept" ref="dept"/>
<constructor-arg name="password" value="男" />

第四种方法：直接传值直接给参数赋值，这种方法也是根据顺序排的，所以一旦调换位置的话，就会出现bug这种方法已经很原始了

<constructor-arg  value="zhangsan" />
<constructor-arg  value="10086" />
<constructor-arg  ref="dept"/>
<constructor-arg  value="男" />
</bean>

当然无论上那种方法 Dept也是需要对应的

<bean id="dept" class="www.csdn.spring01.constructor.Dept" >

<property name="dname" value="北航"/>
<property name="deptno" value="00001"/>
</bean>

同样的所有的配置都要写在

<bean></beans>

那么另外一种就是 property：通过setxx方法注入。 

public class Doctor {

private String name;
private String sex;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getSex() {
return sex;
}

public void setSex(String sex) {
this.sex = sex;
}

public void init(){
System.out.println("88888888888");
}
public void init(String name,String sex){
this.name = name;
this.sex = sex;
}
}

<pre name="code" class="html">  <bean id="doctor" class="com.spring.test.man.Doctor" init-method="init">
<property name="name" value="doctor"></property>
<property name="sex" value="i don't know"></property>
</bean>

tips 在这里我配置了一个init-method="init"表示在容易实例化这个doctor的时候，调用一个Doctor类的init方法，本来还以为可以通过这个init方法来注入要注入的信息，但是尝试过后才知道这个init方法是不能带参数的。 

以上就是整个配置文件的所有目录的 后面估计会写一些标签的用法和具体的例子吧 其实很多都是网上找到 但是东西万变不离其中 我这里只是理了一下思路 借花献佛 顺便自己留一个笔记 将来不会了 还可以来找
