seata 1.2 版本实战过程踩坑记：

1、

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70][]

2、如何自己修改源码后打包seata-server

A. 删除 distribution 模块的bin、conf和lib目录。

B. ./mvnw clean install -DskipTests=true(Mac,Linux) 或 mvnw.cmd clean install -DskipTests=true(Win) -P release-seata。

C. 在 distribution 模块的 target 目录下解压相应的压缩包即可。

3、io.seata.codec.protobuf.generated不存在，导致seata server启动不了?

**A:** 本地执行下: `./mvnw clean install -DskipTests=true` (Mac,Linux)

或   `mvnw.cmd clean install -DskipTests=true` (Win), [参考issues/2438][issues_2438],相关代码在0.8.1已经移除。

4、

5、seata 1.2对应 springboot 、springCloud和springCloudAlibaba 版本如下：

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.2.5.RELEASE</version>
            <relativePath/> 
        </parent>
    
    
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-seata</artifactId>
                <exclusions>
                    <exclusion>
                        <groupId>io.seata</groupId>
                        <artifactId>seata-spring-boot-starter</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>io.seata</groupId>
                <artifactId>seata-spring-boot-starter</artifactId>
               <version>1.2.0</version>
            </dependency>
    
    
      <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>Hoxton.SR3</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>2.2.0.RELEASE</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

版本必须对应，否则会出现各种问题，比如springboot版本为2.1.7RELEASE（就低了一个版本），其他cloud和alibaba版本不变，会出现潜藏的问题。

如：A服务调用B服务，B服务没有产生分支事务（seata服务中没有生成相应的事务branch\_table和锁lock\_table数据，B客户端表undo\_log没有生成反sql，即事务ID没有传到B服务），这类问题非常难以排查，必须借助官网、源码和对应版本一一核对。我们微服务项目组就出现过类似问题，我排查了一个下午，才得以解决。

类似问题：我配置的client端，单独的都能够成功回滚，并且有seata的xid，但是用feign调用模块时，只有第一个模块能回滚，这是什么问题啊？？

这类列出一些最近spring生态相关版本对应：

目前`Spring Cloud Alibaba`的版本与`Spring Boot`、`Spring Cloud`版本的兼容关系：

目前`Spring Cloud Alibaba`的版本与`Sentinel`、`Nacos` 、`RocketMQ` 、`Dubbo`、`Seata`版本的兼容关系：

五、连接nacos  ：seata 注册到 nacos , 在 seata 时报如下错误:

原因是因为配置 nacos 地址时, 在后面多加了一个** / **

报错配置：去掉反斜杠就OK了。

六、 出现这个问题了，怎么解决？

[https://blog.csdn.net/weixin\_41905537/article/details/107664386][https_blog.csdn.net_weixin_41905537_article_details_107664386]

修改地址:sh seata-server.sh -p 8091 -h 10.130.66.188   即和Linux服务器ip地址保持一致即可！切记！!

七、.Nacos 作为 Seata 配置中心时，项目启动报错找不到服务（win和linux环境）。如何排查，如何处理?

异常：io.seata.common.exception.FrameworkException: can not register RM,err:can not connect to services-server.

排查可能的原因：

1.  查看nacos配置列表，seata配置是否已经导入成功
2.  查看nacos服务列表，serverAddr是否已经注册成功
3.  检查client端的registry.conf里面的namespace，registry.nacos.namespace和config.nacos.namespace填入nacos的命名空间ID，默认""，server端和client端对应，namespace 为public是nacos的一个保留控件，如果您需要创建自己的namespace，最好不要和public重名，以一个实际业务场景有具体语义的名字来命名
4.  nacos上服务列表，serverAddr地址对应ip地址应为seata启动指定ip地址，如：sh [seata-server.sh][] -p 8091 -h 122.51.204.197 -m file
5.  查看seata/conf/nacos-config.txt 事务分组service.vgroupMapping.trade\_group=default配置与项目分组配置名称是否一致
6.  telnet ip 端口 查看端口是都开放，以及防火墙状态

八、编译启动源码时 报错：io.seata.codec.protobuf.generated不存在，导致seata server启动不了?

io.seata.codec.protobuf.generated 源码找到这个微服务删除就OK了。

官方答案：

本地执行下: `./mvnw clean install -DskipTests=true` (Mac,Linux) 或 `mvnw.cmd clean install -DskipTests=true` (Win), [参考issues/2438][issues_2438],相关代码在0.8.1已经移除。
