Spring、基本类型属性和集合类型属性的注入

来源：互联网发布：修改linux时间编辑：程序博客网时间：2024/04/28 09:02

Spring 还可以对基本属性和集合类型属性进行注入：

public interface PersonIService {public String getBaseProperty();public Set<String> getSets();public List<Integer> getList();public Properties getProperties();public Map<String, String> getMaps();}

public class PersonServiceImpl implements PersonIService {private String baseProperty;private Set<String> sets;private List<Integer> list;private Properties properties;private Map<String,String> maps;public Map<String, String> getMaps() {return maps;}public void setMaps(Map<String, String> maps) {this.maps = maps;}public Properties getProperties() {return properties;}public void setProperties(Properties properties) {this.properties = properties;}public List<Integer> getList() {return list;}public void setList(List<Integer> list) {this.list = list;}public Set<String> getSets() {return sets;}public String getBaseProperty() {return baseProperty;}public void setBaseProperty(String baseProperty) {this.baseProperty = baseProperty;}public void setSets(Set<String> sets) {this.sets = sets;}}

beans.xml:

<bean id="personIService" class="cn.server.impl.PersonServiceImpl"><property name="baseProperty" value="value:基本属性1" /><property name="sets"><set><value>set装配-value1</value><value>set装配-value2</value><value>set装配-value3</value></set></property><property name="list"><list><value>11</value><value>12</value><value>13</value></list></property><property name="properties"><props><prop key="property1">value1</prop><prop key="property2">value2</prop><prop key="property3">value3</prop></props></property><property name="maps"><map><entry key="map1" value="value1" /><entry key="map2" value="value2" /><entry key="map3" value="value3" /></map></property></bean>

测试代码：

@Testpublic void otherTest(){ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");PersonIService personIService=(PersonIService)ac.getBean("personIService");System.out.println("========基本属性注入============");System.out.println(personIService.getBaseProperty());System.out.println("========Set集合类型注入============");for(String str : personIService.getSets()){System.out.println(str);}System.out.println("========list集合类型注入============");for(Integer i : personIService.getList()){System.out.println(i);}System.out.println("========properties集合类型注入============");for(Object key : personIService.getProperties().keySet()){System.out.println(key+"="+personIService.getProperties().getProperty(key.toString()));}System.out.println("========map集合类型注入============");for(Object key : personIService.getMaps().keySet()){System.out.println(key+"="+personIService.getMaps().get(key));}}
