Spring4.0 xml显示配置（构造器参数注入，属性注入）

项目目录：

package paraBean;public class AnoBean {void play(){System.out.println("i am abbean");}}

package paraBean;public class CtBean {void play(){System.out.println("i am ctbean");}}

package paraBean;public interface Disk {void play();}

package paraBean;import java.util.List;public class JayDiskImpl implements Disk {//注入bean,字符串，集合三种类型private CtBean cb;private AnoBean ab;private String str;private List<String>strlist;private List<Object>blist; //以上用于构造器注入属性 //以下用于setter属性注入private CtBean cbn;private String setStr;private List<String>setStrlist;private List<Object>setObjlist;public CtBean getCbn() {return cbn;}public void setCbn(CtBean cbn) {this.cbn = cbn;}public String getSetStr() {return setStr;}public void setSetStr(String setStr) {this.setStr = setStr;}public List<String> getSetStrlist() {return setStrlist;}public void setSetStrlist(List<String> setStrlist) {this.setStrlist = setStrlist;}public List<Object> getSetObjlist() {return setObjlist;}public void setSetObjlist(List<Object> setObjlist) {this.setObjlist = setObjlist;}public JayDiskImpl(CtBean cb,AnoBean ab,String str,List<String>strlist,List<Object>blist){this.cb=cb;this.ab=ab;this.str=str;this.strlist=strlist;this.blist=blist;}public void play() {cb.play();ab.play();System.out.println("I am anotation "+str);for(int i=0;i<strlist.size();i++){System.out.println(strlist.get(i));}for(int i=0;i<blist.size();i++){System.out.println(blist.get(i));}System.out.println("-----------------------------");System.out.println("-----------------------------");cbn.play();System.out.println(setStr);for (int i = 0; i <setStrlist.size(); i++) { System.out.println(setStrlist.get(i));}for (int i = 0; i <setObjlist.size(); i++) { System.out.println(setObjlist.get(i));}}}

package paraBean;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {public static void main(String[] args) {ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("application.xml");ac.getBean("jd", JayDiskImpl.class).play();}}

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:c="http://www.springframework.org/schema/c"  xmlns:p="http://www.springframework.org/schema/p"  xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd   http://www.springframework.org/schema/util  http://www.springframework.org/schema/util/spring-util.xsd">  <bean id="cb" class="paraBean.CtBean"> </bean> <bean id="ab" class="paraBean.AnoBean"> </bean> <bean id="jd" class="paraBean.JayDiskImpl"> <constructor-arg  ref="cb"/> <constructor-arg  ref="ab"/> <constructor-arg  value="注入的字符串"/> <constructor-arg> <list> <value>我是注入集合1</value> <value>我是注入集合2</value> </list> </constructor-arg> <constructor-arg> <list> <ref bean="ab"/> <ref bean="cb"/> </list> </constructor-arg>  <property name="cbn" ref="cb"/> <property name="setStr" value="i am 属性字符串"/> <property name="setStrlist"> <list>  <value>属性字符串1</value>  <value>属性字符串2</value> </list> </property> <property name="setObjlist"> <list> <ref bean="ab"/> <ref bean="cb"/> </list> </property> </bean> </beans>

运行test 控制台输出：

i am ctbean
i am abbean
I am anotation 注入的字符串
我是注入集合1
我是注入集合2
paraBean.AnoBean@40c06c8b
paraBean.CtBean@19163ae3
-----------------------------
-----------------------------
i am ctbean
i am 属性字符串
属性字符串1
属性字符串2
paraBean.AnoBean@40c06c8b
paraBean.CtBean@19163ae3

现在xml中的配置用c 和p标签分别来代替 construct 和property 属性标签:

此时xml头部为

<beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:c="http://www.springframework.org/schema/c"  xmlns:p="http://www.springframework.org/schema/p"  xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd   http://www.springframework.org/schema/util  http://www.springframework.org/schema/util/spring-util.xsd">

c和p标签无法像construct和property 那样直接嵌入集合，那么就使用一种折中的方法，将list 转成bean对象，然后在c和p标签中直接引用：

好现在来看看整个配置文件：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:c="http://www.springframework.org/schema/c"  xmlns:p="http://www.springframework.org/schema/p"  xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd   http://www.springframework.org/schema/util  http://www.springframework.org/schema/util/spring-util.xsd">  <bean id="cb" class="paraBean.CtBean"> </bean> <bean id="ab" class="paraBean.AnoBean"> </bean> <util:list id="strlist"> <value>注入集合1</value> <value>注入集合2</value> </util:list> <util:list id="blist"> <ref bean="ab"/> <ref bean="cb"/> </util:list> <bean id="jd" class="paraBean.JayDiskImpl" c:cb-ref="cb"  c:ab-ref="ab" c:str="c string" c:strlist-ref="strlist"  c:blist-ref="blist" p:cbn-ref="cb" p:setStr="i am p string"  p:setStrlist-ref="strlist" p:setObjlist-ref="blist">  <!--<constructor-arg  ref="cb"/> <constructor-arg  ref="ab"/> <constructor-arg  value="注入的字符串"/> <constructor-arg> <list> <value>我是注入集合1</value> <value>我是注入集合2</value> </list> </constructor-arg> <constructor-arg> <list> <ref bean="ab"/> <ref bean="cb"/> </list> </constructor-arg>  <property name="cbn" ref="cb"/> <property name="setStr" value="i am 属性字符串"/> <property name="setStrlist"> <list>  <value>属性字符串1</value>  <value>属性字符串2</value> </list> </property> <property name="setObjlist"> <list> <ref bean="ab"/> <ref bean="cb"/> </list> </property> --> </bean> </beans>

最后输出：

i am ctbean
i am abbean
I am anotation c string
注入集合1
注入集合2
paraBean.AnoBean@75227d3
paraBean.CtBean@22b49166
-----------------------------
-----------------------------
i am ctbean
i am p string
注入集合1
注入集合2
paraBean.AnoBean@75227d3
paraBean.CtBean@22b49166
