Spring Tutorial VII Spring injection list

1, the main configuration modification is two points, one is the XML configuration file, the other is the bean injection.

       <bean id= "Jack" class= "Com.test.pro.Singer" >      <property name= "Language" >      <list>      < value> English </value>      <value> Chinese </value>      <value> Japanese </value>      </list >      </property>  </bean>

2. Bean class

Package Com.test.pro;import Java.util.list;public class Singer {private list<string> language;public list< String> GetLanguage () {return language;} public void SetLanguage (List<string> language) {this.language = language;} public void saying () {for (String s:language) {System.out.println ("I will language +" +s);}}

3. Test class

Package Com.test.pro;import Org.springframework.context.applicationcontext;import Org.springframework.context.support.classpathxmlapplicationcontext;public class Main {public static void Main (String [] args) {//TODO auto-generated method Stubapplicationcontext ctx=new classpathxmlapplicationcontext ("Spring.xml"); Singer singer= (Singer) Ctx.getbean ("Jack"); Singer.saying ();}}

Output results

To summarize, injecting complex key points is actually the value of the XML config file property.
