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
<mapper namespace="com.zhaochao.mapper.UserMapper">
<cache readOnly="true" eviction="FIFO" flushInterval="60000" />
<resultMap id="BaseResultMap" type="com.zhaochao.bean.User">

- eclipse 直接在Main.java中run as java application
- 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
