## `SpringBoot`集成`Hession`

### 0. `Hession`简介

`Hessian`是一个二进制的`Web Service`协议，有了它使用`Web Service`再也不需要一个很大的框架，学习一套新的协议，因为它是一个二进制协议。他很适合用来发送二进制数据。
`Hession`由`Caucho Technology`公司开发，在开源协议下，他们已经发布了很多语言的`Hession`实现，第三方的实现还包括`C++`，`C#`，`Javascript`等，也都是开源的。

在进行基于`Hessian`的项目开发时，应当注意以下几点：

1. `JAVA`服务器端必须具备以下几点:
   - 包含`Hessian`的jar包
   - 设计一个接口，用来给客户端调用
   - 实现该接口的功能
   - 由于使用二进制RPC协议传输数据，对象必须进行序列化，实现`Serializable`接口
   - 对于复杂对象可以使用Map的方法传递
2. 客户端必须具备以下几点
   - `JAVA`客户端包含`Hessian.jar`的包
   - 具有和服务器端结构一样的接口。包括命名空间都最好一样
   - 利用`HessianProxyFactory`调用远程接口
   
### 1. 开发准备

在本例子中，我们在`IEDA`中创建一个`Maven`多模块项目，项目名为`hession`，包含两个模块`hession-server`和`hession-client`,如下：

```xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.mbigger</groupId>
    <artifactId>hession</artifactId>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>hession-server</module>
        <module>hession-client</module>
    </modules>

</project>
```

### 2.服务端开发

2.1. 新建`Maven`模块，类型为`Spring boot`项目，引入依赖:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.mbigger</groupId>
    <artifactId>hession-server</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>hession-server</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.caucho</groupId>
            <artifactId>hessian</artifactId>
            <version>4.0.60</version>
        </dependency>


        <dependency>

            <artifactId>spring-boot-devtools</artifactId>

        </dependency>

        </dependency>

            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>
```

2.2. 新建接口`HessionService`:
```java
package com.mbigger.hessionserver;

public interface HessionService {
    String sayHello();
    String chat();
    String sayByebye();
}
```

2.3. 实现`HessionService`接口
```java
package com.mbigger.hessionserver;

import org.springframework.stereotype.Service;

@Service("hessionService")
public class HessionServiceImpl implements HessionService{
    @Override
    public String sayHello() {
        return "hello, guys!!!";
    }

    @Override
    public String chat() {
        return "balabala~@#%^!~";
    }

    @Override
    public String sayByebye() {
        return "Bye bye!";
    }
}
```

2.4. 发布接口
```java
package com.mbigger.hessionserver;

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;

@Configuration
public class HessionServiceConfig {

    @Autowired
    private HessionService hessionService;

    @Bean("/hessionService")
    public HessianServiceExporter hessionService() {
        HessianServiceExporter exporter = new HessianServiceExporter();
        exporter.setService(hessionService);
        exporter.setServiceInterface(HessionService.class);
        return exporter;
    }
}
```

### 3 客户端开发

3.1 新建`Maven`模块，类型为`SpringBoot`项目, 此处注意，要引入`hession-server`模块的依赖，以使用对方发布的接口方法：
```xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.mbigger</groupId>
    <artifactId>hession-client</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>hession-client</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.caucho</groupId>
            <artifactId>hessian</artifactId>

        </dependency>
        <dependency>
            <groupId>com.mbigger</groupId>
            <artifactId>hession-server</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>


        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>
```

3.2 配置`Hession`代理对象：
```java
package com.mbigger.hessionclient;

import com.mbigger.hessionserver.HessionService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.remoting.caucho.HessianProxyFactoryBean;

@Configuration
public class HessianClientConfig {
    @Bean
    public HessianProxyFactoryBean helloClient() {
        HessianProxyFactoryBean factory = new HessianProxyFactoryBean();
        factory.setServiceUrl("http://localhost:9000/hessionService");
        factory.setServiceInterface(HessionService.class);
        return factory;
    }
}
```

3.3 创建`Controller`,并调用远程服务方法，以便测试
```java
package com.mbigger.hessionclient;

import com.mbigger.hessionserver.HessionService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HessionClientController {
    @Autowired
    private HessionService hessionService;

    @GetMapping("/sayHello")
    public String sayHello(){
        return hessionService.sayHello();
    }

    @GetMapping("/chat")
    public String chat(){
        return hessionService.chat();
    }

    @GetMapping("/sayByebye")
    public String sayByebye(){
        return hessionService.sayByebye();
    }
}
```

### 4. 运行并验证
