Problems encountered in upgrading

• spring boot 2.2.0 bug, resulting in incompatible and mybatis 3.5.2

Official Issue: github.com/spring-proj...
constructor injection problem, mybatis private constructor can not bind the property, causing other dependent mybatisframe types mybatis-plussuch problems gitee.com/baomidou/my...

Failed to bind properties under 'mybatis-plus.configuration.incomplete-result-maps[0].assistant.configuration.mapped-statements[0].parameter-map.parameter-mappings[0]' to org.apache.ibatis.mapping.ParameterMapping
复制代码

• Solution:
  We recompiled the mybatis 3.5.2, mybatis-plus 3.2.0 modify some source code compatible private constructor into public, maven modify the coordinates

<dependency>
    <groupId>com.pig4cloud</groupId>
    <artifactId>mybatis-plus</artifactId>
<version>3.2.0</
复制代码

to sum up

• The use of the Spring Cloud RCversions are not synced to the cloud and other domestic Ali mirror factory library

mvn clean install
复制代码

Failure may occur, best to repeat a few times

---

• Given the incompatibility Spring Boot 2.2.0 and mybatis and 2.2.1 will fix this problem, the proposed temporary do not directly use the upgrade 2.2.0 2.2.1

2.2.1 has been released, you can upgrade directly to 2.2.1 to resolve compatibility issues (07 November 2019 supplement)
