基于javaConfig的springDataJpa+dubbo+springMvc搭建(一)

很遗憾dubbo的几个创始人好像不维护dubbo了，最近有些人更新到了2.8.4:http://code.taobao.org/p/dubbox/src/trunk/dubbox/
dubbo的官网:http://dubbo.io/

此maven项目分三个子模块:sdk,app和web.其中sdk主要放一些公共的文件,app和web都依赖sdk.
一.在sdk模块:声明一个接口

package org.exam.sdk.service;import org.exam.sdk.domain.User;/** * Created by xin on 15.12.27. */public interface UserService {    User save(User user);}

二.在app模块:
1.实现这个接口(在这里不赘述spring data jpa的使用)

package org.exam.app.service;import com.alibaba.dubbo.config.annotation.Service;import org.exam.sdk.domain.User;import org.exam.app.repository.UserRepository;import org.exam.sdk.service.UserService;import org.springframework.beans.factory.annotation.Autowired;/** * Created by xin on 15.12.27. */@Servicepublic class UserServiceImpl implements UserService {    @Autowired    private UserRepository userRepository;    @Override    public User save(User user){        return userRepository.save(user);    }}

2.写单元测试

package org.exam.app.service;import org.exam.app.config.AppConfig;import org.exam.sdk.base.ObjectId;import org.exam.sdk.domain.User;import org.exam.sdk.service.UserService;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.annotation.Rollback;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.support.AnnotationConfigContextLoader;import org.springframework.transaction.annotation.Transactional;/** * Created by xin on 2015/12/27. */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(loader=AnnotationConfigContextLoader.class,classes={AppConfig.class})@Transactional(transactionManager = "transactionManager")public class UserServiceTest {    @Autowired    private UserService userService;    @Test    @Rollback(false)    public void testInitData(){        User user=new User();        user.setId(new ObjectId().toString());        user.setUsername("username");        user.setPassword("password");        user.setEnable(true);        userService.save(user);    }}

三.在web模块:
1.单元测试,看一下userService是否注入成功

package org.exam.web.service;import com.alibaba.dubbo.config.annotation.Reference;import org.exam.sdk.service.UserService;import org.exam.web.config.AppConfig;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;/** * Created by xin on 2015/12/27. */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(classes={AppConfig.class})public class UserServiceTest {    @Reference    private UserService userService;    @Test    public void testSave(){        System.out.println("userService = " + userService);    }}

2.在controller使用

package org.exam.web.controller;import com.alibaba.dubbo.config.annotation.Reference;import org.exam.sdk.domain.User;import org.exam.sdk.service.UserService;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping("user")public class UserController {    @Reference    private UserService userService;    @RequestMapping(value = "save")    public String save(User user) {        if (user.getId()==null){            user.setId(new Object().toString());        }        userService.save(user);        return "user/test";    }}

四.再看看最关键的配置:
1.app的主要配置

package org.exam.app.config;import com.alibaba.dubbo.config.ApplicationConfig;import com.alibaba.dubbo.config.RegistryConfig;import com.alibaba.dubbo.config.spring.AnnotationBean;import com.mchange.v2.c3p0.ComboPooledDataSource;import org.springframework.context.EnvironmentAware;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;import org.springframework.core.env.Environment;import org.springframework.data.jpa.repository.config.EnableJpaRepositories;import org.springframework.orm.jpa.JpaTransactionManager;import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;import org.springframework.orm.jpa.vendor.Database;import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;import org.springframework.transaction.PlatformTransactionManager;import org.springframework.transaction.annotation.EnableTransactionManagement;import javax.sql.DataSource;import java.beans.PropertyVetoException;/** * Created by xin on 15.12.27. */@Configuration@PropertySource("classpath:config.properties")@EnableTransactionManagement@EnableJpaRepositories(basePackages = {"org.exam.app.repository"})public class AppConfig implements EnvironmentAware {    private Environment env;    @Override    public void setEnvironment(Environment environment) {        env = environment;    }    /*与<dubbo:annotation/>相当.提供方扫描带有@com.alibaba.dubbo.config.annotation.Service的注解类*/    @Bean    public static AnnotationBean annotationBean() {        AnnotationBean annotationBean = new AnnotationBean();        annotationBean.setPackage("org.exam.app.service");//所以含有@com.alibaba.dubbo.config.annotation.Service的注解类都应在此包中,多个包名可以使用英文逗号分隔.        return annotationBean;    }    /*与<dubbo:application/>相当.*/    @Bean    public ApplicationConfig applicationConfig() {        ApplicationConfig applicationConfig = new ApplicationConfig();        applicationConfig.setLogger("slf4j");        applicationConfig.setName(env.getProperty("dubbo.applicationName"));        return applicationConfig;    }    /*与<dubbo:registry/>相当*/    @Bean    public RegistryConfig registryConfig() {        RegistryConfig registryConfig = new RegistryConfig();        registryConfig.setAddress(env.getProperty("dubbo.registryAddress"));        return registryConfig;    }    /*与<dubbo:protocol/>相当*/    @Bean    public ProtocolConfig protocolConfig(){        ProtocolConfig protocolConfig=new ProtocolConfig("dubbo",20880);        protocolConfig.setSerialization("java");//默认为hessian2,但不支持无参构造函数类,而这种方式的效率很低        return protocolConfig;    }    @Bean(destroyMethod = "close")    public DataSource dataSource() {        ComboPooledDataSource dataSource = new ComboPooledDataSource();        try {            dataSource.setDriverClass(env.getProperty("db.driverClass"));        } catch (PropertyVetoException e) {            e.printStackTrace();        }        dataSource.setJdbcUrl(env.getProperty("db.jdbcUrl"));        dataSource.setUser(env.getProperty("db.user"));        dataSource.setPassword(env.getProperty("db.password"));        dataSource.setInitialPoolSize(Integer.valueOf(env.getProperty("db.initialPoolSize")));        dataSource.setAcquireIncrement(Integer.valueOf(env.getProperty("db.acquireIncrement")));        dataSource.setMinPoolSize(Integer.valueOf(env.getProperty("db.minPoolSize")));        dataSource.setMaxPoolSize(Integer.valueOf(env.getProperty("db.maxPoolSize")));        dataSource.setMaxIdleTime(Integer.valueOf(env.getProperty("db.maxIdleTime")));        dataSource.setIdleConnectionTestPeriod(Integer.valueOf(env.getProperty("db.idleConnectionTestPeriod")));        return dataSource;    }    @Bean    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();        jpaVendorAdapter.setDatabase(Database.valueOf(env.getProperty("jpa.database")));        jpaVendorAdapter.setGenerateDdl(Boolean.parseBoolean(env.getProperty("jpa.generateDdl")));        jpaVendorAdapter.setShowSql(Boolean.parseBoolean(env.getProperty("jpa.showSql")));        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();        emf.setDataSource(dataSource());        emf.setPackagesToScan("org.exam.sdk.domain");        emf.setJpaVendorAdapter(jpaVendorAdapter);        return emf;    }    @Bean    public PlatformTransactionManager transactionManager() {        JpaTransactionManager transactionManager = new JpaTransactionManager();        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());        return transactionManager;    }}

app模块的config.properties

#DATABASE STARTdb.driverClass=com.mysql.jdbc.Driverdb.jdbcUrl=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8db.user=rootdb.password=123456#db.driverClass=oracle.jdbc.driver.OracleDriver#db.jdbcUrl=jdbc:oracle:thin:@127.0.0.1:1521:orcl#db.user=ieco2o#db.password=ieco2odb.initialPoolSize=5db.acquireIncrement=3db.minPoolSize=3db.maxPoolSize=50db.maxIdleTime=60db.idleConnectionTestPeriod=120#DATABASE END#JPA STARTjpa.generateDdl=truejpa.showSql=true#DEFAULT,DB2,DERBY,H2,HSQL,INFORMIX,MYSQL,ORACLE,POSTGRESQL,SQL_SERVER,SYBASEjpa.database=MYSQL#JPA END#DUBBO STARTdubbo.applicationName=provider-mall-appdubbo.registryAddress=zookeeper://127.0.0.1:2181#DUBBO END

2.web的主要配置

package org.exam.web.config;import com.alibaba.dubbo.config.ApplicationConfig;import com.alibaba.dubbo.config.RegistryConfig;import com.alibaba.dubbo.config.spring.AnnotationBean;import org.springframework.context.EnvironmentAware;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;import org.springframework.core.env.Environment;/** * Created by xin on 15/12/27. */@Configuration@PropertySource("classpath:config.properties")@ComponentScan(basePackages = "org.exam.web.controller")public class AppConfig implements EnvironmentAware {    private Environment env;    @Override    public void setEnvironment(Environment environment) {        env = environment;    }    /*与<dubbo:annotation/>相当.提供方扫描带有@com.alibaba.dubbo.config.annotation.Reference的注解类*/    @Bean    public static AnnotationBean annotationBean() {        AnnotationBean annotationBean = new AnnotationBean();        annotationBean.setPackage("org.exam.web.service,org.exam.web.controller");        return annotationBean;    }    /*与<dubbo:application/>相当.*/    @Bean    public ApplicationConfig applicationConfig() {        ApplicationConfig applicationConfig = new ApplicationConfig();        applicationConfig.setLogger("slf4j");        applicationConfig.setName(env.getProperty("dubbo.applicationName"));        return applicationConfig;    }    /*与<dubbo:registry/>相当*/    @Bean    public RegistryConfig registryConfig() {        RegistryConfig registryConfig = new RegistryConfig();        registryConfig.setAddress(env.getProperty("dubbo.registryAddress"));        return registryConfig;    }    /*与<dubbo:protocol/>相当*/    @Bean    public ProtocolConfig protocolConfig(){        ProtocolConfig protocolConfig=new ProtocolConfig("dubbo",20880);        protocolConfig.setSerialization("java");//默认为hessian2,但不支持无参构造函数类,而这种方式的效率很低        return protocolConfig;    }     /*dubbo end*/}

web模块的config.properties

#DUBBO STARTdubbo.applicationName=consumer-mall-webdubbo.registryAddress=zookeeper://127.0.0.1:2181#DUBBO END

五.其它不重要的,就省略,过行测试.先启动zookeeper(即使开发环境,注册中心也不使用广播,因为不稳定),再启动app的单元测试是否正常,再启动App,再启动web的单元测试是否正常,最后测试controller是否注入成功.
