1.配置文件：
web配置：
<context-param><br /> <param-name>contextConfigLocation</param-name><br /> <param-value>classpath*:applicationContext.xml</param-value>//在类文件下查找配置文件：applicationContext.xml<br /> </context-param></p> <p> <listener><br /> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class><br /> </listener>
<bean id="check" class="quanquanfly.Check" init-method="init" destroy-method="destroy"/> //初始化spring时自动运行 quanquanfly.Check中的init方法
2.注入：
<bean id="test" class="quanquanfly.Test" /><br /> <bean id= "testimpl" class="quanquanfly.TestImpl"><br /> <property name="test" ref="test"/><br /> </bean>
junit测试：
@Test public void test()<br /> {<br /> ApplicationContext act = new ClassPathXmlApplicationContext("applicationContext.xml");<br /> TestImpl test = (TestImpl)act.getBean("testimpl");<br /> test.saveimpl();<br /> }
3.使用注解进行注入：
<context:annotation-config />
@Resource(name = "test")<br /> public Test test;// @Resource先根据名字test到配置文件中查找，找不到在通过类型Test进行查找注入<br /> @Resource<br /> public Test test;<br /> @Autowired<br /> public Test test1;// @Autowired默认按类型进行查找注入<br /> @Autowired<br /> @Qualifier("test")<br /> public Test test2;// 更改默认按类型为按test名字进行查找注入
4.自动扫描class管理bean：
<context:component-scan base-package="quanquanfly"/>
扫描的类应该含有@Repository@Controller@Service等标记
@Service("testimpl")//设置bean名字为testimpl，默认为类名第一字母小写testImpl<br /> public class TestImpl {<br /> //@Resource(name="test") public Test test;//@Resource先根据名字test到配置文件中查找，找不到在通过类型Test进行查找注入<br /> //@Autowired public Test test1;//@Autowired默认按类型进行查找注入<br /> //@Autowired @Qualifier("test") public Test test2;//更改默认按类型为按test名字进行查找注入<br /> @Resource public Test test;<br /> public void saveimpl()<br /> {<br /> test.save();<br /> }<br /> }
4.aop：

@Aspect@Repository<br /> public class Check1 {<br /> @Pointcut("execution(* quanquanfly.TestImpl.*(..))")//声明切入点<br /> public void anyMethod(){}</p> <p> @Before("anyMethod()")//定义前置通知<br /> public void before()<br /> {<br /> System.out.println("前置通知");<br /> }<br /> @AfterReturning("anyMethod()")//定义后置通知<br /> public void afterreturn()<br /> {<br /> System.out.println("后置通知");<br /> }</p> <p> @After("anyMethod()")//定义后置通知<br /> public void after()<br /> {<br /> System.out.println("最终通知");<br /> }</p> <p> @AfterThrowing("anyMethod()")//出现例外通知的时候，不出现后置通知，其他通知都可以执行<br /> public void throwing()<br /> {<br /> System.out.println("例外通知");<br /> }</p> <p> @Around("anyMethod()")<br /> public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {<br /> System.out.println("进入方法");<br /> Object result = pjp.proceed();<br /> System.out.println("退出方法");<br /> return result;<br /> }<br /> }
