一、hessianserver
1.pom.xml添加hessian依赖

<dependency>
    <groupId>com.caucho</groupId>
    <artifactId>hessian</artifactId>
    <version>4.0.38</version>
</dependency>

2.实现service接口，方便发布服务

@Service
public class ConfigService implements IConfigService {

	private final ConcurrentSkipListMap<Long, Config> configs = new ConcurrentSkipListMap<Long, Config>();

	private static final AtomicLong idSequence = new AtomicLong(1000L);

	@Override
	public ResultBean<Long> addConfig(Config config) {
		System.out.println("addConfig：" + config);
		
		long id = idSequence.incrementAndGet();

		config.setId(id);
		configs.put(id, config);

		return new ResultBean<>(id);
	}

	@Override
	public ResultBean<Collection<Config>> getAll() {
		return new ResultBean<>(configs.values());
	}

	@Override
	public ResultBean<Boolean> delete(long id) {
		return new ResultBean<>(configs.remove(id) != null);
	}

}

3.发布hessian服务

/**
 * 发布Config的Hessian服务
 * 
 */
@Configuration
public class HessianConfig {
	@Autowired
	private IConfigService configService;

	@Bean(name = "/ConfigService")
	public HessianServiceExporter hessianServiceExporter() {
		HessianServiceExporter exporter = new HessianServiceExporter();

		exporter.setService(configService);
		exporter.setServiceInterface(IConfigService.class);

		return exporter;
	}
}

二、hessianclient
1.pom.xml添加hessian依赖

<dependency>
    <groupId>com.caucho</groupId>
    <artifactId>hessian</artifactId>
    <version>4.0.38</version>
</dependency>

2.HessianProxyFactoryBean 引入服务

@Configuration
public class HessianConfig {

	@Bean
	public HessianProxyFactoryBean helloClient() {
		HessianProxyFactoryBean factory = new HessianProxyFactoryBean();

		factory.setServiceUrl("http://localhost:8080/ConfigService");
		factory.setServiceInterface(IConfigService.class);

		return factory;
	}
}

3.junit测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class HessianclientApplicationTests {

	@Autowired
	IConfigService configService;

	@Test
	public void configTest() {
		ResultBean<Long> addResult = configService
				.addConfig(Config.builder().name("配置项名称").value("配置项值").build());
		System.out.println(addResult);

		ResultBean<Collection<Config>> all = configService.getAll();
		System.out.println(all);

		// 把刚刚新建的删除掉
		ResultBean<Boolean> deleteResult = configService.delete(addResult.getData());
		System.out.println(deleteResult);
	}

}```
