SpringBoot之统一事务管理配置

SpringBoot之自定义Jackson反序列化日期类型转换配置类

统一事务管理配置

1. SpringBoot版本

 <parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.5.RELEASE</version></parent>
<dependencies><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.9.7</version></dependency></dependencies>

2. 统一事务管理配置类

package com.yuan.webframework.config;import org.aspectj.lang.annotation.Aspect;
import org.springframework.aop.Advisor;
import org.springframework.aop.aspectj.AspectJExpressionPointcut;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionDefinition;
import org.springframework.transaction.interceptor.DefaultTransactionAttribute;
import org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource;
import org.springframework.transaction.interceptor.TransactionInterceptor;/*** <p>* Description: 统一事务管理配置* </p>** @author jinshengyuan* @since 2022/8/5 16:35*/
@Aspect
@Configuration
public class TransactionManagerConfig {//切点表达式private static final String AOP_POINT_EXPRESSION = "execution(* com.zx.*.**.service.impl.*.*(..))  or execution(* org.snaker.engine..*.*(..))";@AutowiredPlatformTransactionManager transactionManager;//注入平台(Mybatis)事务管理器@Beanpublic TransactionInterceptor txAdvice(){//增删改DefaultTransactionAttribute txRequired = new DefaultTransactionAttribute();txRequired.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);txRequired.rollbackOn(new Throwable());txRequired.setIsolationLevel(TransactionDefinition.ISOLATION_READ_COMMITTED);//除了指定前缀开头的以外，其他方法也支持事务DefaultTransactionAttribute txRequiredAll = new DefaultTransactionAttribute();txRequiredAll.setPropagationBehavior(TransactionDefinition.PROPAGATION_SUPPORTS);txRequiredAll.rollbackOn(new Throwable());txRequiredAll.setIsolationLevel(TransactionDefinition.ISOLATION_READ_COMMITTED);//查DefaultTransactionAttribute txRequiredReadOnly = new DefaultTransactionAttribute();txRequiredReadOnly.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);txRequiredReadOnly.setReadOnly(true);NameMatchTransactionAttributeSource source = new NameMatchTransactionAttributeSource();//切入点切入以下的方法为事务方法source.addTransactionalMethod("add*",txRequired);source.addTransactionalMethod("save*",txRequired);source.addTransactionalMethod("insert*",txRequired);source.addTransactionalMethod("update*",txRequired);source.addTransactionalMethod("modify*",txRequired);source.addTransactionalMethod("delete*",txRequired);source.addTransactionalMethod("change*",txRequired);source.addTransactionalMethod("move*",txRequired);source.addTransactionalMethod("remove*",txRequired);source.addTransactionalMethod("submit*",txRequired);source.addTransactionalMethod("distribute*",txRequired);source.addTransactionalMethod("cancel*",txRequired);source.addTransactionalMethod("batch*",txRequired);source.addTransactionalMethod("sync*",txRequired);source.addTransactionalMethod("set*",txRequired);source.addTransactionalMethod("*",txRequiredAll);//切入点切入的以下的方法为只读事务方法source.addTransactionalMethod("get*",txRequiredReadOnly);source.addTransactionalMethod("query*",txRequiredReadOnly);source.addTransactionalMethod("select*",txRequiredReadOnly);source.addTransactionalMethod("count*",txRequiredReadOnly);source.addTransactionalMethod("find*",txRequiredReadOnly);source.addTransactionalMethod("search*",txRequiredReadOnly);source.addTransactionalMethod("is*",txRequiredReadOnly);return  new TransactionInterceptor(transactionManager,source);}//事务切入点@Beanpublic Advisor txAdviceAdvisor(){AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();pointcut.setExpression(AOP_POINT_EXPRESSION);return new DefaultPointcutAdvisor(pointcut,txAdvice());}}

3. 主启动类加入开启事务的注解

如主启动类中加入@EnableTransactionManagement注解，如下

package com.yuan;import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;@Slf4j
@EnableTransactionManagement
@SpringBootApplication
public class MyApplication {public static void main(String[] args) throws UnknownHostException {SpringApplication.run(MyApplication.class, args);}
}
