Spring boot 集成hessian - LocalDateTime序列化和反序列化

- 反序列化

import com.caucho.hessian.HessianException;
import com.caucho.hessian.io.AbstractDeserializer;
import com.caucho.hessian.io.AbstractHessianInput;
import com.caucho.hessian.io.IOExceptionWrapper;

import java.io.IOException;
import java.time.LocalDateTime;
import java.time.ZoneOffset;

public class LocalDateTimeDeserializer extends AbstractDeserializer {

    @Override
    public Class getType()
    {
        return LocalDateTime.class;
    }

    @Override
    public Object readObject(AbstractHessianInput in,
                             Object []fields)
            throws IOException
    {
        String []fieldNames = (String []) fields;

        int ref = in.addRef(null);

        long initValue = Long.MIN_VALUE;

        for (int i = 0; i < fieldNames.length; i++) {
            String key = fieldNames[i];

            if (key.equals("value")) {
                initValue = in.readUTCDate();
            } else {
                in.readObject();
            }
        }
        Object value = create(initValue);
        in.setRef(ref, value);
        return value;
    }

    private Object create(long initValue)
            throws IOException
    {
        if (initValue == Long.MIN_VALUE) {
            throw new IOException(LocalDateTime.class + " expects name.");
        }
        try {
            return LocalDateTime.ofEpochSecond(new Long(initValue)/1000,Integer.valueOf(String.valueOf(initValue%1000))*1000,ZoneOffset.of("+8"));
        } catch (Exception e) {
            throw new IOExceptionWrapper(e);
        }
    }
}

- 序列化

import com.caucho.hessian.io.AbstractHessianOutput;
import com.caucho.hessian.io.AbstractSerializer;

import java.io.IOException;
import java.time.LocalDateTime;
import java.time.ZoneOffset;

/**
 * @author zenglw
 * @date 2018/6/7
 */
public class LocalDateTimeSerializer extends AbstractSerializer {

    @Override
    public void writeObject(Object obj, AbstractHessianOutput out)
            throws IOException
    {
        if (obj == null) {
            out.writeNull();
        } else {
            Class cl = obj.getClass();

            if (out.addRef(obj)) {
                return;
            }
            // ref 返回-2 便是开始写Map
            int ref = out.writeObjectBegin(cl.getName());

            if (ref < -1) {
                out.writeString("value");
                Long milliSecond = ((LocalDateTime) obj).toInstant(ZoneOffset.of("+8")).toEpochMilli();
                out.writeUTCDate(milliSecond);
                out.writeMapEnd();
            } else {
                if (ref == -1) {
                    out.writeInt(1);
                    out.writeString("value");
                    out.writeObjectBegin(cl.getName());
                }

                Long milliSecond = ((LocalDateTime) obj).toInstant(ZoneOffset.of("+8")).toEpochMilli();
                out.writeUTCDate(milliSecond);
            }
        }
    }
}

- hessian的序列化工厂

import com.caucho.hessian.io.ExtSerializerFactory;
import com.caucho.hessian.io.SerializerFactory;
import com.klxx.ta.common.util.hessian.LocalDateTimeDeserializer;
import com.klxx.ta.common.util.hessian.LocalDateTimeSerializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author zenglw
 * @date 2018/6/7
 */
@Configuration
public class HessianConfig {

    @Bean
    public SerializerFactory serializerFactory() {
        // DO 自定义hessian反序列化
        // step 1. 定义外部序列化工厂
        ExtSerializerFactory extSerializerFactory = new ExtSerializerFactory();
        extSerializerFactory.addSerializer(java.time.LocalDateTime.class,new LocalDateTimeSerializer());
        extSerializerFactory.addDeserializer(java.time.LocalDateTime.class,new LocalDateTimeDeserializer());
        // step 2. 序列化工厂
        SerializerFactory serializerFactory = new SerializerFactory();
        serializerFactory.addFactory(extSerializerFactory);
        return serializerFactory;
    }
}

- hessian服务端暴露服务

import com.caucho.hessian.io.SerializerFactory;
import com.klxx.ta.foundation.api.OrganizationInfoApi;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.remoting.caucho.HessianServiceExporter;

/**
 * Hessian注册对外提供服务的service
 * @author zenglw
 * @date 2018/6/4
 */
@Configuration
public class HessianExportConfig {

    @Autowired
    private OrganizationInfoApi organizationInfoApi;

    @Bean(name = "organizationInfoApi")
    public HessianServiceExporter accountService(SerializerFactory serializerFactory) throws Exception {
        HessianServiceExporter exporter = new HessianServiceExporter();
        exporter.setSerializerFactory(serializerFactory);
        exporter.setService(organizationInfoApi);
        exporter.setServiceInterface(OrganizationInfoApi.class);
        return exporter;
    }

}

- hessian客户端的服务代理配置

import com.caucho.hessian.io.SerializerFactory;
import com.klxx.ta.foundation.api.OrganizationInfoApi;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.remoting.caucho.HessianProxyFactoryBean;

/**
 * @author zenglw
 * @date 2018/6/7
 */
@Configuration
public class HessianProxyConfig {

    @Value("${hessian.external.service.url.foundation}")
    private String foundationUrl;

    @Bean(name = "accountServiceApi")
    public HessianProxyFactoryBean accountServiceApi(SerializerFactory serializerFactory) {
        HessianProxyFactoryBean hessianProxyFactoryBean = new HessianProxyFactoryBean();
        hessianProxyFactoryBean.setSerializerFactory(serializerFactory);
        hessianProxyFactoryBean.setServiceUrl(foundationUrl + "/organizationInfoApi");
        hessianProxyFactoryBean.setServiceInterface(OrganizationInfoApi.class);
        return hessianProxyFactoryBean;
    }
}
