However, in accepting such obligations, You may act only 170 | on Your own behalf and on Your sole responsibility, not on behalf 171 | of any other Contributor, and only if You agree to indemnify, 172 | defend, and hold each Contributor harmless for any liability 173 | incurred by, or claims asserted against, such Contributor by reason 174 | of your accepting any such warranty or additional liability. 175 | 176 | END OF TERMS AND CONDITIONS 177 | 178 | APPENDIX: How to apply the Apache License to your work. 179 | 180 | To apply the Apache License to your work, attach the following 181 | boilerplate notice, with the fields enclosed by brackets "{}" 182 | replaced with your own identifying information. (Don't include 183 | the brackets!) The text should be enclosed in the appropriate 184 | comment syntax for the file format. We also recommend that a 185 | file or class name and description of purpose be included on the 186 | same "printed page" as the copyright notice for easier 187 | identification within third-party archives. 188 | 189 | Copyright {yyyy} {name of copyright owner} 190 | 191 | Licensed under the Apache License, Version 2.0 (the "License"); 192 | you may not use this file except in compliance with the License. 193 | You may obtain a copy of the License at 194 | 195 | http://www.apache.org/licenses/LICENSE-2.0 196 | 197 | Unless required by applicable law or agreed to in writing, software 198 | distributed under the License is distributed on an "AS IS" BASIS, 199 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 200 | See the License for the specific language governing permissions and 201 | limitations under the License. 202 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 关于事务的控制，有一下几点说明： 2 | 3 | 目前说的事务是基于DB的事务 4 | 既然如此，跨DB的事务不能支持的。因为相当于一个操作包含了两个事务。这种场景很明显是分布式事务的场景 5 | 6 | 7 | 1、采用申明或者注解实现事务控制时时，因为开启了事务控制，所以如果是两个不同的数据源Dao， 8 | 根据spring的事务传播特性，第二个事务开启将使用已有的事务（即将采用第一个数据源的数据库连接）进行事务操作， 9 | 所以此时事务控制是失效的（即使切面执行了数据源切换）。 10 | 结论就是跨数据库的事务是无法通过spring的数据库控制实现的！！！请切记。 11 | 12 | 2、同一个数据源的事务控制和普通的数据源控制是一致的，没有什么区别。 13 | 14 | 15 | ![微信扫描二维码，关注我的公众号](https://user-images.githubusercontent.com/13701989/97533659-94da1680-19f3-11eb-9530-528f0eb82585.png) 16 |

This makes sense in the end, but it tripped me up for a bit. 30 | So just to reiterate, if you want to turn off the Spring Boot database initialization, set the following in your application.properties: 31 | # Disable Spring DataSource auto-initialization 32 | spring.datasource.initialize=false 33 | https://www.ccampo.me/java/spring/2016/02/13/multi-datasource-spring-boot.html 34 | 35 | 36 | 问题2： 37 | 显示开户事务：@EnableTransactionManagement 38 | 原理现在还没有搞清楚，怀疑是设置spring.datasource.initialize=false为false后,导致PlatformTransactionManager也没有自动启动 39 | 40 | 网上见到的错误用法1：使用AutoConfigureAfter来确定Bean之间的依赖 41 | @AutoConfigureAfter only controls the ordering of auto-configuration classes and has no effect on dependency injection. 42 | It also only affects auto-configuration classes so may we'll be doing nothing on your Assembly class. 43 | http://stackoverflow.com/questions/39717450/explanation-of-configuration-autoconfigureafter-with-kotlin 44 | 45 | todo: 46 | 动态数据源重复代码剥离：@Primary 47 | not aop 48 | 49 | 50 | 51 | 52 | 53 | -------------------------------------------------------------------------------- /mybatis-aop/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 6 | springboot-multi-datasource 7 | com.tangcheng 8 | 0.0.1-SNAPSHOT 9 | ../pom.xml 10 | 11 | 4.0.0 12 | 13 | mybatis-aop 14 | 15 | 3.3.1 16 | 1.2.4 17 | 3.3.8 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | org.mybatis 27 | mybatis 28 | ${mybatis.version} 29 | 30 | 31 | org.mybatis 32 | mybatis-spring 33 | ${mybatis.spring.version} 34 | 35 | 36 | 37 | tk.mybatis 38 | mapper 39 | ${mapper.version} 40 | 41 | 42 | 43 | org.mybatis.generator 44 | mybatis-generator-core 45 | 1.3.2 46 | compile 47 | true 48 | 49 | 50 | 51 | 52 | 53 | 54 | -------------------------------------------------------------------------------- /mybatis-aop/src/main/java/com/tangcheng/datasources/aop/MybatisAopApplication.java: -------------------------------------------------------------------------------- 1 | package com.tangcheng.datasources.aop;
