ram const 準備 調用 spring 1.0 sch cto xmlns 1、首先準備共享文件
調用方法Client端Client.java:
調用方法Client端Client.java:
import org.springframework.context.support.ClassPathXmlApplicationContext; public class Client { public static void main(String[] args) { //創建容器 ClassPathXmlApplicationContext cac = new ClassPathXmlApplicationContext("service.xml"); //獲取bean對象 CustomerServiceImpl cs = (CustomerServiceImpl) cac.getBean("CustomerServiceImpl"); //調用方法 cs.saveCustomer(); } }
接口文件CustomerService.java:
public interface CustomerService {
void saveCustomer();
}
2、構造函數方式註入:
Spring配置文件,Service.xml:
<?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.xsd"> <bean id="CustomerServiceImpl" class="CustomerServiceImpl"> <constructor-arg name="name" value="zhangsan"></constructor-arg> <constructor-arg name="age" value="3"></constructor-arg> </bean> </beans>
註入bean類文件:CustomerServiceImpl.java
public class CustomerServiceImpl implements CustomerService { private String name ; private Integer age; public CustomerServiceImpl(String name, Integer age) { this.name = name; this.age = age; } @Override public void saveCustomer() { System.out.println("CustomerServiceImpl-saveCustomer-" + name + "-" + age); } }
3、set方法註入
Spring配置文件,Service.xml:
<?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.xsd">
<bean id="CustomerServiceImpl" class="CustomerServiceImpl">
<property name="name" value="李四"></property>
<property name="age" value="10"></property>
</bean>
</beans>
註入bean類文件:CustomerServiceImpl.java:
public class CustomerServiceImpl implements CustomerService {
private String name ;
private Integer age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public void saveCustomer() {
System.out.println("CustomerServiceImpl-saveCustomer-" + name + "-" + age);
}
}
