[Solved] Notwritablepropertyexception: invalid property ‘mapperhelper’ of bean class

Problem:
The project integration of generic mapper when starting an error, first look at the error message, the project starts with the following error.
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property ‘mapperHelper’ of bean class [org.mybatis.spring.mapper.MapperFactoryBean]: Bean property ‘mapperHelper’ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Error Log:

There are too many error messages. Take a look at the main error messages

Error analysis

It can be seen from the error message that a parameter name called mapperhelper needs to be configured when integrating the general mapper. Before LZ, the project integration method is the same, but this one can’t be used. So I thought about whether the compatibility between springboot and mapper is a problem, so I changed the 3.4.0 version of general mapper to 4.1.5 version. After downloading the dependency again, the project started successfully. So I suggest you change the version of general mapper. In addition, netizens on the Internet said that it was caused by hot deployment. You can turn it off in the POM file, but the pro test is invalid. If you want to know how to configure it, you can check this post: springboot integrates general mapper and mybatis (sub module project)

The timeout parameter of the configuration file is set to 0. Meanwhile, testOnReturn, testWhileIdle and testOnBorrow are configured to be true. However, when I tried, I failed to solve the problem.

1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

Redis has given three solutions: SET protected-mode no
New protected-mode configuration after Redis3.2, default is yes, that is, on. The effect of protected-mode setting to different values is as follows:
At this point, the external network can directly access
. To enable the protected protection-mode, configure the bind IP or set the access password.
The developer has been using Redis 3.0 and this time redIS 5.0.7 is used on the server
Set the protected-mode in the configuration file to no problem resolution. It seems that you should read the error log carefully when you encounter problems
