SpringCould集成seata
版本
<spring.cloud-version>2020.0.3</spring.cloud-version>
<spring.boot-version>2.5.1</spring.boot-version>
<spring.cloud.alibaba-version>2021.1</spring.cloud.alibaba-version>
<seata-version>1.4.2</seata-version>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.25</version>
</dependency>
mysql版本是8.0.25时报上述错误，研究发现此seata版本版本引入的com.alibaba.druid版本是1.1.23，
查看源码，在druid源码MySqlUtils类中执行了createXAConnection()方法；而成员变量method_6_getBooleanReadableProperty是通过反射去获去mysql-connect-java包中的com.mysql.cj.api.conf.PropertySet接口中的getBooleanReadableProperty()方法
try {
if (class_6_connection == null) {
class_6_connection = Class.forName("com.mysql.cj.jdbc.JdbcConnection");
method_6_getPropertySet = class_6_connection.getMethod("getPropertySet");
method_6_getBooleanReadableProperty = Class.forName("com.mysql.cj.conf.PropertySet").getMethod("getBooleanReadableProperty", String.class);
method_6_getValue = Class.forName("com.mysql.cj.conf.ReadableProperty").getMethod("getValue");
}else {
method_6_getPropertySet = class_6_connection.getMethod("getPropertySet");
method_6_getBooleanReadableProperty = Class.forName("com.mysql.cj.api.conf.PropertySet").getMethod("getBooleanReadableProperty", String.class);
method_6_getValue = Class.forName("com.mysql.cj.api.conf.ReadableProperty").getMethod("getValue");
}
} catch (Exception ex) {....}
再查看mysql-connect-java包中的com.mysql.cj.api.conf.PropertySet接口，在8.0.25版本中，此接口并没有getBooleanReadableProperty()方法，所以返回null；接着MySqlUtils方法继续执行
Boolean pinGlobTx = (Boolean) method_6_getValue.invoke(
method_6_getBooleanReadableProperty.invoke(
method_6_getPropertySet.invoke(physicalConn)
, "pinGlobalTxToPhysicalConnection"
)
);
可以发现method_6_getBooleanReadableProperty变量调用了invoke方法，最终抛出异常；
目前解决方案是把mysql-connect-java版本退回到8.0.11，成功执行并回滚全局事务
