项目总体目录结构

项目结构说明

com.zhaochao.action 主要放处理RESTFull 接口业务，代码如下所示

@Path("user")
public class UserAction {
    @Autowired
    private UserService userService;
    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public User getGreeting(@PathParam("id") Integer id) throws Exception {
        return userService.getUserById(id);
    }
}

com.zhaochao.bean 主要放数据表对应实体对象

public class User {
    private Integer id;
    private String name;
    private Integer age;
    private String password;
    //省去getter setter 方法
}

对应数据库表脚本如下：

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `age` int(11) NOT NULL,
  `password` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

INSERT INTO `user` VALUES ('1', 'zhaochao', '20', 'zhaochao');
INSERT INTO `user` VALUES ('2', '赵云', '50', 'zhaoyun');

com.zhaochao.main 存放项目配置文件和主函数

ApplicationConfig jersey的配置文件

public class ApplicationConfig extends ResourceConfig {
    public ApplicationConfig() {
        packages("com.zhaochao.action");
        register(JacksonFeature.class);
        property(ServerProperties.METAINF_SERVICES_LOOKUP_DISABLE, true);
    }
}

主要指明Jersey 的资源存放在com.zhaochao.action包下，以及将返回对象直接转换成JSON

SpringJavaConfiguration Spring的配置文件，相当于applicationcontext.xml

@Component
@Configuration
@ComponentScan(basePackages = {"com"})
public class SpringJavaConfiguration {
    @Bean(autowire = Autowire.BY_TYPE)
    public DataSource dataSource() {
        PoolProperties poolProperties = new PoolProperties();
        poolProperties.setDriverClassName("com.mysql.jdbc.Driver");
        poolProperties.setUrl("jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false&maxReconnects=10");
        poolProperties.setUsername("root");
        poolProperties.setPassword("root");
        poolProperties.setJmxEnabled(true);
        poolProperties.setJdbcInterceptors("org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer");
        poolProperties.setRemoveAbandonedTimeout(60);
        poolProperties.setRemoveAbandoned(true);
        poolProperties.setLogAbandoned(false);
        poolProperties.setMinIdle(10);
        poolProperties.setMinEvictableIdleTimeMillis(30000);
        poolProperties.setMaxWait(10);
        poolProperties.setInitialSize(2);
        poolProperties.setMaxActive(10);
        poolProperties.setTimeBetweenEvictionRunsMillis(30000);
        poolProperties.setValidationQuery("SELECT 1");
        poolProperties.setValidationInterval(30000);
        poolProperties.setTestOnReturn(false);
        poolProperties.setTestOnBorrow(true);
        poolProperties.setTestWhileIdle(true);
        poolProperties.setJmxEnabled(true);
        DataSource dataSource = new DataSource();
        dataSource.setPoolProperties(poolProperties);
        return dataSource;
    }


    @Bean(name="sqlSessionFactory" )
    public SqlSessionFactoryBean getSqlSesssionFactoryBean(){
        SqlSessionFactoryBean bean=new SqlSessionFactoryBean();
        bean.setDataSource(dataSource());
        Resource re =new ClassPathResource("mybatis-config.xml");
        bean.setConfigLocation(re);
        return bean;
    }
    @Bean(name="mapper",autowire=Autowire.BY_NAME)
    public MapperScannerConfigurer getMapperScannerConfigurer(){
        MapperScannerConfigurer conf=new MapperScannerConfigurer();
        conf.setBasePackage("com.zhaochao.mapper");
        conf.setSqlSessionFactoryBeanName("sqlSessionFactory");
        return conf;
    }

Main 项目启动主函数

public class Main {
    public static void main(String[] args) throws Exception {
        ApplicationConfig applicationConfig = new ApplicationConfig();
        ServletHolder jerseyServlet = new ServletHolder(new ServletContainer(applicationConfig));
        ServletContextHandler context = new ServletContextHandler();
        context.setContextPath("/");
        context.addServlet(jerseyServlet, "/rest/*");
        context.addEventListener(new ContextLoaderListener());
        context.addEventListener(new RequestContextListener());
        context.setInitParameter("contextClass", AnnotationConfigWebApplicationContext.class.getName());
        context.setInitParameter("contextConfigLocation", SpringJavaConfiguration.class.getName());
        int port=8080;
        if(args.length==1){
            port=Integer.parseInt(args[0]);
        }
        Server server = new Server(port);
        server.setHandler(context);
        try {
            server.start();
            server.join();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

com.zhaochao.mapper Mybatis 接口

public interface UserMapper {
    @Select("select * from user where id=#{id}")
    public User getUserById(@Param("id") Integer id);
    public User queryById(Integer id);  
}

com.zhaochao.service user服务类

@Service("userService")
public class UserService  {
    @Autowired
    private UserMapper mapper;
    public UserMapper getMapper() {
        return mapper;
    }
    public User getUserById(Integer userId){
        //return mapper.getUserById(userId);
        return mapper.queryById(userId);
    }
}

src/main/resource 存放Mybatis配置文件

mybatis/user/UserMapper 这是UserMapper的映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

        select
        <include refid="Base_Column_List" />
        from user where id = #{id}
    </select>
</mapper>   

mybatis-config.xml mybatis 配置文件

运行项目

1. eclipse 直接在Main.java中run as java application
2. 用maven 打开jar包后，在项目的target 目录中找到jersey-spring-jetty-1.0-SNAPSHOT.jar通过以下命令启动项目

java -jar jersey-spring-jetty-1.0-SNAPSHOT.jar

测试项目

打开浏览器输入http://localhost:8080/rest/user/1
