I have read a lot on the Internet, and it is said that because of the multi-tenant function in the MyBatis_Plus framework, MP will filter data permissions, but I have tried it and found that it does not work. Remember that I have encountered this problem before, because of the package. It is caused by the version, but I forgot it, so I will write it down this time, lest I forget it again.

reason:

The mybatis-plus package conflicts with the original pagehelper com.github.jsqlparser:jsqlparser

solution:

solve:

1. Exclude the jsqlparser package in other dependencies, introduce a new jsqlparser, or exclude only one of them, and use another jsqlparser package without re-importing

Exclude jsqlparser in pageHelper

            <dependency>
                <groupId>com.github.pagehelper</groupId>
                <artifactId>pagehelper-spring-boot-starter</artifactId>
                <version>${pagehelper.boot.version}</version>
                <exclusions>
                    <!-- 解决jsqlparser 依赖版本冲突-->
                    <exclusion>
                        <artifactId>jsqlparser</artifactId>
                        <groupId>com.github.jsqlparser</groupId>
                    </exclusion>
                </exclusions>
            </dependency>

Exclude jsqlparser in Mybatis-Plus

        <!-- mybatis-plus 增强CRUD -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.1</version>
            <exclusions>
                <!-- 解决jsqlparser 依赖版本冲突&ndash;&gt;-->
                <exclusion>
                    <artifactId>jsqlparser</artifactId>
                    <groupId>com.github.jsqlparser</groupId>
                </exclusion>                      				
            </exclusions>
        </dependency>

Introduce new jsqlparser

        <dependency>
            <groupId>com.github.jsqlparser</groupId>
            <artifactId>jsqlparser</artifactId>
            <version>4.2</version>
        </dependency>

2. Modify the version of MyBatis-plus or pageHelper package, the version of Mybatis-Plus I use here is 3.4.1, and the version of pageHelper is 1.3.0

 

You can adjust the version, order or exclude conflicting jar packages according to the maven dependency principle
