spring 配置文件中如何注入map list set等类型

先定义一个bean

import java.util.List;import java.util.Map;import java.util.Properties;import java.util.Set;public class MessageBean {private String username;private String password;private int size;private List<String> citys;private Set<String> friends;private Map<Integer,String> books;private Properties props;public void setProps(Properties props) {this.props = props;}public void setFriends(Set<String> friends) {this.friends = friends;}public void setSize(int size) {this.size = size;}public void setPassword(String password) {this.password = password;}public void setUsername(String username) {this.username = username;}public void setCitys(List<String> citys) {this.citys = citys;}public void setBooks(Map<Integer, String> books) {this.books = books;}}

在xml里配置

<beans><bean id="userdao" class="com.user.impl.UserDAO"></bean><!-- setter方式注入 --><bean id="useraction" class="com.action.UserAction"> <property name="userDao" ref="userdao"> </property></bean><!-- 构造器方式注入 --><bean id="useraction1" class="com.action.UserAction2"> <constructor-arg index="0" ref="userdao"/></bean><!-- 各种类型值注入的写法 --><bean id="messagebean" class="com.bean.MessageBean"><property name="props"><props><prop key="url">http://www.sina.com.cn</prop><prop key="username">lisi</prop><prop key="password">123456</prop></props></property><property name="books"><map><entry key="10" value="playboy"></entry><entry key="11" value="java"></entry><entry key="12" value="rdis"></entry></map></property><property name="friends"><set><value>张3</value><value>李4</value><value>王5</value></set></property><property name="citys"><list><value>北京</value><value>上海</value><value>广州</value></list></property><property name="username"><value>admin</value></property><property name="password"><value>123456</value></property><property name="size"><value>25</value></property></bean></beans>
