java Spring集合

在进行输入的时候一定要给属性配置set方法，因为不设置是注入不了的。

1.list

UserService.java

private ArrayList arr;
    public ArrayList getArr() {
    return arr;
}
public void setArr(ArrayList arr) {
    this.arr = arr;
}

service.xml

 <bean name="userService" class="com.sun.service.UserService">
    <property name="name" >
          <value>sunxin</value>
    </property>
    <property name="arr">
        <list> 
          <value>Tom</value>
          <value>Jack</value>
          <value>Jeson</value>
        </list>
    </property>
</bean>

2.map

private Map<String, Float> accounts;
    
    public void setAccounts(Map<String, Float> accounts) {
        this.accounts = accounts;
    }

service.xml

<beans>
    <bean id="foo" class="com.sun.service.UserService">
        <property name="accounts">
            <map>
                <entry key="one" value="9.99"/>
                <entry key="two" value="2.75"/>
                <entry key="six" value="3.99"/>
            </map>
        </property>
    </bean>
</beans>
