Spring、基本类型属性和集合类型属性的注入

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：

@Test
public 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));
}
}
