1： 首先给service添加集合类型的属性，并提供getter, setter
package cn.gbx.serviceimpl; import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set; import cn.gbx.daoimpl.PersonDao;
import cn.gbx.service.PersonService; public class PersonServiceImpl implements PersonService {
private Set<String> sets = new HashSet<String>();
private List<String> list = new ArrayList<String>();
private Map<String, String> maps = new HashMap<String, String>();
private Properties properties = new Properties(); private PersonDao personDao;
private String name;
private Integer id; public void save() {
System.out.println("id = " + id + "name = " + name);
personDao.save();
System.out.println("service : " + " save 方法");
} public PersonDao getPersonDao() {
return personDao;
}
public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
} public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public Integer getId() {
return id;
} public void setId(Integer id) {
this.id = id;
} public Set<String> getSets() {
return sets;
} public void setSets(Set<String> sets) {
this.sets = sets;
} public List<String> getList() {
return list;
} public void setList(List<String> list) {
this.list = list;
} 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;
} }
2: 配置xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <bean id="personDaoImpl" class="cn.gbx.dao.PersonDaoImpl"></bean>
<bean id="personServiceImpl" class="cn.gbx.serviceimpl.PersonServiceImpl" >
<property name="personDao" ref="personDaoImpl"></property>
<property name="name" value="ok-gbx"></property>
<property name="id" value="22"></property> <property name="list">
<list>
<value>valu1</value>
<value>valu2</value>
<value>valu3</value>
</list>
</property> <property name="sets">
<set>
<value>value-1</value>
<value>value-2</value>
<value>value-3</value>
</set>
</property> <property name="maps">
<map>
<entry key="key1" value="value1"></entry>
<entry key="key2" value="value2"></entry>
<entry key="key3" value="value3"></entry>
</map>
</property> <property name="properties">
<props>
<prop key="key1">value1</prop>
<prop key="key2">value2</prop>
<prop key="key3">value3</prop>
</props>
</property>
</bean>
</beans>
3： 测试：
public class SpringTest {
@Test
public void spring1() {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
PersonService ps = (PersonService)ctx.getBean("personServiceImpl");
ps.save();
System.out.println("--------List-------------");
for (String s : ps.getList()) {
System.out.println(s);
}
System.out.println("--------sets-------------");
for (String s : ps.getSets()) {
System.out.println(s);
}
System.out.println("--------maps-------------");
for (String key : ps.getMaps().keySet()) {
System.out.println(key + " : " + ps.getMaps().get(key));
}
System.out.println("--------propertis-------------");
for (Object key : ps.getProperties().keySet()) {
System.out.println(key + " : " + ps.getMaps().get(key));
}
}
@Test
public void spring2() {
MyClassPathXmlApplicationContext ctx = new MyClassPathXmlApplicationContext("beans.xml");
PersonService ps = (PersonService)ctx.getBean("personServiceImpl");
ps.save();
System.out.println();
}
}
