搭建jersey+mybits+spring框架

1.首先将需要的依赖加入到本地资源库

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

2.配置applicationContent.xml也就是配置spring.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"    xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"    xmlns:jpa="http://www.springframework.org/schema/data/jpa"    xsi:schemaLocation="        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd        http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"><!-- 配置数据源 -->    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>        <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:orcl"/>        <property name="username" value="system"/>        <property name="password" value="admin"/>        <!--连接池启动时的初始值 -->        <property name="initialSize" value="10"/>        <!--连接池的最大值 -->        <property name="maxActive" value="100"/>        <!--最大空闲值.当经过一个高峰时间后，连接池可以慢慢将已经用不到的连接慢慢释放一部 分，一直减少到maxIdle为止 -->        <property name="maxIdle" value="50"/>        <!--最小空闲值.当空闲的连接数少于阀值时，连接池就会预申请去一些连接，以免洪峰来时 来不及申请 -->        <property name="minIdle" value="10"/>        <!--给出一条简单的sql语句进行验证 -->        <property name="validationQuery" value="select 1 from dual"/>        <!--在取出连接时进行有效验证 -->        <property name="testOnBorrow" value="true"/>        <property name="removeAbandonedTimeout" value="120"/>        <property name="removeAbandoned" value="true"/>        <!--#运行判断连接超时任务的时间间隔，单位为毫秒，默认为-1，即不执行任务.-->        <property name="timeBetweenEvictionRunsMillis" value="3600000"/>        <!--#连接的超时时间，默认为半小时。-->        <property name="minEvictableIdleTimeMillis" value="3600000"/>    </bean>    <!-- 配置mybatisSqlSessionFactoryBean -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">         <!-- 数据连接池 -->        <property name="dataSource" ref="dataSource" />        <!--加载mybits全局配置文件   configlocation指定mybits的xml配置文件的路径-->        <property name="configLocation" value="classpath:mybatis-config.xml"></property>    </bean>        <!-- DAO接口所在包名，Spring会自动查找其下的类，注入到Spring容器中 -->     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.cj.dao"></property>        <!-- 用sqlSessionFactoryBeanName的原因是为了防止sqlSessionFactory提前被初始化 -->        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>     </bean>     <!--扫描service  -->     <context:component-scan base-package="com.cj.service">    </context:component-scan>     <!-- 扫描controller -->     <context:component-scan base-package="com.cj">        <context:exclude-filter type="regex"            expression="com.cj.resource" />     </context:component-scan> </beans>

3.写一个jersey的资源注册类,里面就是转换数据和将你的资源暴露

package com.cj;import javax.ws.rs.ApplicationPath;import org.glassfish.jersey.server.ResourceConfig;import org.glassfish.jersey.server.mvc.jsp.JspMvcFeature;import org.glassfish.jersey.moxy.json.MoxyJsonFeature;import com.cj.resource.UserController;import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider;public class RestApplication extends ResourceConfig{    public RestApplication(){          //加载resource      register(UserController.class);      //注册 JSON 转换器         register(MoxyJsonFeature.class);        register(JacksonJsonProvider.class);        register(JspMvcFeature.class);//注册MVC支持        //jsp文件所在位置，当前JSP文件是在项目根目录下        property(JspMvcFeature.TEMPLATE_BASE_PATH,"/");     }   }

4.最后配置web.xml

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app>     <!-- 定义站台的名称 -->  <display-name>Archetype Created Web Application</display-name>  <!-- 设置上下文参数  声明应用范围内的初始化参数-->        <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>  <!-- 定义spring监听器，加载spring -->    <listener>        <listener-class>            org.springframework.web.context.ContextLoaderListener        </listener-class>    </listener>    <!-- 加载jersey资源 -->   <servlet>         <servlet-name>Jersey Web Application</servlet-name>         <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>         <init-param>             <param-name>javax.ws.rs.Application</param-name>             <param-value>com.cj.RestApplication</param-value>         </init-param>         <load-on-startup>1</load-on-startup>         <async-supported>true</async-supported>     </servlet>     <!-- 映射器 -->    <servlet-mapping>     <servlet-name>Jersey Web Application</servlet-name>         <url-pattern>/cj/*</url-pattern>     </servlet-mapping>       <welcome-file-list>        <welcome-file>/index.jsp</welcome-file>    </welcome-file-list></web-app>

5.最后测试：

//根资源,相当于mvc里面的maaping@Path("/")public class UserController {    @Autowired    BaseService BaseService    //表示被标记的方法是什么样的请求    @GET    //相当于一个子资源，用来找具体的方法。    @Path("/index")    public String index(){        return "123123";    }    }

输入路径http://localhost:8080/cj/index
如果页面上出现123123，搭建成功！
