# spring
1. spring jar包导入
```Java
导入如下包并添加到内路径
spring-beans-4.1.7.RELEASE.jar
spring-context-4.1.7.RELEASE.jar
spring-core-4.1.7.RELEASE.jar
spring-expression-4.1.7.RELEASE.jar
spring-test-4.1.7.RELEASE.jar
commons-logging-1.1.3.jar
```
2. spring的配置文件
```xml
```
3. 为依赖的属性提供get/set方法
```Java
package test;
public class A {
private B b3 = new B();//class A 依赖 class B 依赖的属性一定要实例化
// B b3;//class A 依赖 class B
private C c3;
public C getC3() {
return c3;
}
public void setC3(C c3) {
this.c3 = c3;
}
public int add(String a,String b) {
int c = 0;
int a1 = Integer.parseInt(a);
int b1 = Integer.parseInt(b);
return b3.add(a1, b1);
}
public void sayHello(String username) {
c3.print(username);
}
public static void main(String[] args) {
System.out.println(new A().add("12","13"));
}
}
```
```Java
package test;
public class C {
public void print(String name) {
System.out.println("hello," + name);
}
}
```
4. 测试
```Java
package test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
public static void main(String[] args) {
ClassPathXmlApplicationContext act = new ClassPathXmlApplicationContext("applicationContext.xml");
// A a = new A();
A a = (A) act.getBean("a");
a.sayHello("liyiqiang");
}
}
```
**测试结果:**
```
hello,liyiqiang
```
