### 2.spring-bean.xml ###

<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" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" 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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="oracle.jdbc.OracleDriver" />
            <property name="url" value="jdbc:oracle:thin:localhost:1521:orcl" />
            <property name="username" value="scott" />
            <property name="password" value="tiger" />
        </bean>
    
        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
                    <prop key="hibernate.show_sql">true</prop>
                </props>
            </property>
            
            <property name="packagesToScan" value="cn">
            </property>
        </bean>
    
        <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
            <property name="sessionFactory" ref="sessionFactory" />
        </bean>
    
        <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />
    
        
        <mvc:interceptors>
            <bean class="org.springframework.orm.hibernate4.support.OpenSessionInViewInterceptor">
                <property name="sessionFactory" ref="sessionFactory" />
            </bean>
        </mvc:interceptors>
    </beans>

### 3.配置spring-servlet.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" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        
        <context:component-scan base-package="cn" />
    
        
        <mvc:annotation-driven />
    
        
        <mvc:default-servlet-handler />
    
        
        <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
    
            
            <property name="prefix" value="/" />
    
            
            
            <property name="suffix" value=".jsp" />
        </bean>
    
    </beans>

### 4.配置web.xml文件 ###

<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:spring-*.xml</param-value>
        </init-param>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

### 测试： ###

//只要在页面让其访问dept_find成功即可
        //value写什么就是访问什么
        @RequestMapping(value="dept_find")
        @ResponseBody
        public String find(){
            System.out.println(123);
            List<Dept> list = deptService.queryAll();
            for (Dept dept : list) {
                System.out.println(dept.getDname());
            }
            Gson gson = new Gson();
            return gson.toJson(list);
        }
