# 项目介绍
|
||
|
|
* 基于Netty，实现JT808 808协议、1078协议、苏标、粤标的消息处理，与编码解码；
|
||
|
|
* 无需修改代码，同时支持TCP、UDP协议；
|
||
|
|
* 使用Spring WebFlux 提供支持高并发的Web接口服务；
|
||
|
|
* 不依赖Spring，可移除Spring独立运行（编码解码可支持Android）；
|
||
|
|
* 最简洁、清爽、易用的部标开发框架。
|
||
|
|
|
||
|
|
# 主要特性
|
||
|
|
* 代码足够精简，便于二次开发；
|
||
|
|
* 致敬Spring、Hibernate设计理念，熟悉Web开发的同学上手极快；
|
||
|
|
* 使用注解描述协议，告别繁琐的封包、解包；
|
||
|
|
* 支持异步批量处理，显著提升MySQL入库性能；
|
||
|
|
* 提供报文解释器（解析过程分析工具），编码解码不再抓瞎；
|
||
|
|
* 全覆盖的测试用例，稳定发版。

# 验证步骤
|
||
|
|
|
||
|
|
## 1.验证消息定义
|
||
|
|
解码分析工具：org.yzh.Elucidator（报文 <=> 对象）
|
||
|
|
|
||
|
|
使用src\test\java\Elucidator
|
||
|
|
分析报文内每个属性所处的位置以及转换后的值，以便查询报文解析出错的原因
|
||
|
|
```java
|
||
|
|
package org.yzh;
|
||
|
|
|
||
|
|
public class Elucidator extends JT808Beans {
|
||
|
|
|
||
|
|
public static final JTMessageAdapter coder = new JTMessageAdapter("org.yzh.protocol");
|
||
|
|
|
||
|
|
public static void main(String[] args) {
|
||
|
|
String hex = "020000d40123456789017fff000004000000080006eeb6ad02633df7013800030063200707192359642f000000400101020a0a02010a1e00640001b2070003640e200707192359000100000061646173200827111111010101652f000000410202020a0000000a1e00c8000516150006c81c20070719235900020000000064736d200827111111020202662900000042031e012c00087a23000a2c2a200707192359000300000074706d732008271111110303030067290000004304041e0190000bde31000d90382007071923590004000000006273642008271111110404049d";
|
||
|
|
JTMessage msg = H2019(T0200JSATL12());
|
||
|
|
|
||
|
|
msg = decode(hex);
|
||
|
|
hex = encode(msg);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
Elucidator 运行效果如下：

```
|
||
|
|

|
||
|
|
8. 点击按钮【发送】
|
||
|
|
|
||
|
|
注意：先选择HEX，再粘贴报文
|
||
|
|
```
|
||
|
|
7e0100002e0123456789017fff001f00730000000034000000000000000000000042534a2d47462d30367465737431323301b2e241383838383838157e

# 开发步骤
|
||
|
|
|
||
|
|
## 1.定义消息
|
||
|
|
```java
|
||
|
|
package org.yzh.protocol.t808;
|
||
|
|
|
||
|
|
@Message(JT808.终端注册)
|
||
|
|
public class T0100 extends JTMessage {
|
||
|
|
|
||
|
|
@Field(desc = "省域ID")
|
||
|
|
private short provinceId;
|
||
|
|
@Field(desc = "市县域ID")
|
||
|
|
private short cityId;
|
||
|
|
@Field(length = 11, desc = "制造商ID")
|
||
|
|
private String makerId;
|
||
|
|
@Field(length = 30, desc = "终端型号")
|
||
|
|
private String deviceModel;
|
||
|
|
@Field(length = 30, desc = "终端ID")
|
||
|
|
private String deviceId;
|
||
|
|
@Field(desc = "车牌颜色：0.未上车牌 1.蓝色 2.黄色 3.黑色 4.白色 9.其他")
|
||
|
|
private byte plateColor;
|
||
|
|
@Field(desc = "车辆标识")
|
||
|
|
private String plateNo;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## 2.处理终端上报的消息
|
||
|
|
```java
|
||
|
|
package org.yzh.web.endpoint;
|
||
|
|
|
||
|
|
@Endpoint
|
||
|
|
public class JT808Endpoint {
|
||
|
|
|
||
|
|
@Autowired
|
||
|
|
private DeviceService deviceService;
|
||
|
|
|
||
|
|
@Mapping(types = 0x0100, desc = "终端注册")
|
||
|
|
public T8100 register(T0100 message, Session session) {
|
||
|
|
T8100 result = new T8100();
|
||
|
|
result.setResponseSerialNo(message.getSerialNo());
|
||
|
|
|
||
|
|
DeviceInfo device = deviceService.register(message);
|
||
|
|
if (device != null) {
|
||
|
|
session.register(message);
|
||
|
|
|
||
|
|
result.setToken("1234567890A");
|
||
|
|
result.setResultCode(T8100.Success);
|
||
|
|
} else {
|
||
|
|
result.setResultCode(T8100.NotFoundTerminal);
|
||
|
|
}
|
||
|
|
return result;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## 3.下发消息到终端（通过Web接口）
|
||
|
|
```java
|
||
|
|
package org.yzh.web.controller;
|
||
|
|
|
||
|
|
@RestController
|
||
|
|
@RequestMapping("device")
|
||
|
|
public class JT808Controller {
|
||
|
|
|
||
|
|
@Autowired
|
||
|
|
private MessageManager messageManager;
|
||
|
|
|
||
|
|
@Operation(summary = "8103 设置终端参数")
|
||
|
|
@PutMapping("parameters")
|
||
|
|
public T0001 setParameters(@Parameter(description = "终端手机号") @RequestParam String clientId, @RequestBody Parameters parameters) {
|
||
|
|
Map<Integer, Object> map = parameters.toMap();
|
||
|
|
T8103 request = new T8103(map);
|
||
|
|
T0001 response = messageManager.request(clientId, request, T0001.class);
|
||
|
|
return response;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
注解说明：
|
||
|
|
* @Message，消息类型，等价Hibernate的 @Table
|
||
|
|
* @Field，消息属性，等价Hibernate的 @Column
|
||
|
|
|
||
|
|
* @Endpoint，消息接入点，等价SpringMVC的 @Controller
|
||
|
|
* @Mapping，消息映射到方法，等价SpringMVC中 @RequestMapping
|
||
|
|
* @Async，异步消息处理，用于较为耗时的操作（例如文件写入）。
|
||
|
|
* @AsyncBatch，消息批量处理，对于高并发的消息（例如：位置信息汇报），合并同类消息，提升入库性能。
