Javaweb集成Spring框架

• 1.修改web.xml

    <!--整合spring-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
  
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
  

• 2.创建applicationContent.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"
       xmlns:context="http://www.springframework.org/schema/context"
  
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"
  
       default-lazy-init="false" default-autowire="byName">
  
       <!--开启注解-->
       <context:component-scan base-package="com.azxx"/>
       <!--加载配置文件-->
       <context:property-placeholder location="classpath*:/appConfig.properties" />
     </beans>
  

• 3.测试

• 3.1 创建TestDI.java

    @Component
    public class TestDI {
  
    	//注入配置中的值
        @Value("${jdbc.driver}")
        private String testproperteis;
  
        private static final Logger logger = LogManager.getLogger(TestDI.class);
  
        public TestDI() {
            System.out.println(">>>>>>>>> enter TestDI class constructor");
        }
  
        public int add(int a ,int b){
            return a+b;
        }
  
        public void testMethod(){
            System.out.println(this.testproperteis);
        }
  
    }
  

• 3.2 创建测试类

    /**
     * 将所需加载的xml文件指定为locations的value。如：@ContextConfiguration(locations = { "classpath:Application-Redis.xml" })
     */
    @ContextConfiguration(locations = {"classpath:applicationContext.xml"})
    @RunWith(SpringJUnit4ClassRunner.class)
    public class SpringTestBase extends AbstractJUnit4SpringContextTests {
    }
  
    public class TestDITest extends SpringTestBase {
  
        @Autowired
        private TestDI testDI;
  
        @Test
        public void TestAdd(){
            Assert.assertEquals(4,testDI.add(1,2));
        }
  
        @Test
        public void TestAdd2(){
            Assert.assertEquals(3,testDI.add(1,2));
        }
  
        @Test
        public void testMethod(){
            System.out.println("");
            testDI.testMethod();
        }
    }
  

• 3.3 创建配置文件db.properties

    jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://127.0.0.1:3306/springstudy?characterEncoding=utf-8
    jdbc.username=root
    jdbc.password=shouwang13
  

整合SpringMVC

• 1.修改web.xml,增加以下内容

    <!--configure the setting of springmvcDispatcherServlet and configure the mapping-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--它的值必须是一个整数，表示servlet被加载的先后顺序
        如果该元素的值为负数或者没有设置，则容器会当Servlet被请求时再加载
        如果值为正整数或者0时，表示容器在应用启动时就加载并初始化这个servlet，值越小，servlet的优先级越高，就越先被加载。值相同时，容器就会自己选择顺序来加载。
        -->
         <load-on-startup>1</load-on-startup>
    </servlet>
  
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
  

• 2.创建springmvc.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" xmlns:p="http://www.springframework.org/schema/p"
           xmlns:context="http://www.springframework.org/schema/context"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd ">
  
        <!-- 启用spring mvc 注解 -->
        <context:annotation-config/>
  
        <!-- 设置使用注解的类所在的jar包 -->
        <context:component-scan base-package="com.azxx"/>
  
        <!-- 完成请求和注解POJO的映射 -->
        <!--<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>-->
        　　
        <!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/jsp/" p:suffix=".jsp"/>
    </beans>
