修改file.conf配置文件
1. cd/conf/ 2. vim file.conf 3. 定义tx-service-group: 将vgroup_mapping.my_test_tx_group = "default" 修改为-> vgroup_mapping.my_test_tx_group = "seata-server" 4. 修改store.mode="db" 5. 修改db.datasource="druid" 6. 修改数据库连接的信息 -
修改registry.conf配置文件
1. 修改registry.type="eureka" 2. 修改eureka.serviceUrl为自己eureka地址 3. 修改eureka.applicaton="seata-server" 4. 修改config.type="apollo" 5. 修改config.apollo.app.id="seata-server" 6. 修改config.apollo.apollo.meta为apollo对应地址 -
启动
1. cd/bin/ 2. ./seata-server.sh -p 8091 -n 1 -
启动参数详解
-h: 注册到注册中心的ip -p: Server rpc 监听端口 -m: 全局事务会话信息存储模式，file、db，优先读取启动参数 -n: Server node，多个Server时，需区分各自节点，用于生成不同区间的transactionId，以免冲突 -e: 多环境配置参考 http://seata.io/en-us/docs/ops/multi-configuration-isolation.html
Seata客户端使用
注：seata的配置较多，但是1.0.0版本里面Apollo配置源码只支持使用application的namespace。
- 在pom中增加依赖
com.alibaba.cloud
spring-cloud-alibaba-seata
seata-all
io.seata
io.seata
seata-all
1.0.0
- 将DataSource用seata包内的DataSourceProxy代理
@Primary @Bean("dataSource") public DataSourceProxy dataSourceProxy(DataSource druidDataSource) { return new DataSourceProxy(druidDataSource); } - SqlSessionFactory使用代理后的DataSource
@Bean(name = "sqlSessionFactory") public SqlSessionFactory sqlSessionFactoryBean(DataSourceProxy dataSourceProxy) { SqlSessionFactoryBean bean = new SqlSessionFactoryBean(); bean.setDataSource(dataSourceProxy); bean.setTypeAliasesPackage("com.test.entity"); // 分页插件 PageHelper pageHelper = new PageHelper(); Properties properties = new Properties(); properties.setProperty("reasonable", "true"); // properties.setProperty("supportMethodsArguments", "true"); properties.setProperty("returnPageInfo", "check"); properties.setProperty("params", "count=countSql"); pageHelper.setProperties(properties); MybatisBaseUpdateInterceptor mybatisBaseUpdateInterceptor = new MybatisBaseUpdateInterceptor(); MybatisBaseSelectInterceptor mybatisBaseSelectInterceptor = new MybatisBaseSelectInterceptor(); // 添加插件 bean.setPlugins(new Interceptor[]{pageHelper, mybatisBaseUpdateInterceptor, mybatisBaseSelectInterceptor}); // 添加XML目录 ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); try { bean.setMapperLocations(resolver.getResources("classpath*:mapper/*.xml")); // 设置过滤_ org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration(); configuration.setMapUnderscoreToCamelCase(true); bean.setConfiguration(configuration); return bean.getObject(); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException(e); } } - application.properties增加配置
spring.cloud.alibaba.seata.tx-service-group=my_test_tx_group config.type = apollo registry.type = eureka #seata-server注册的注册中心地址，必填，不填会报错 registry.eureka.serviceUrl = http://xxx.xxx.xxx.xxx:8000/eureka - 数据库创建undo_log表
