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?

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)

Yapi platform deployment error (MAC must report error) solution

1. Deploy Yapi locally

According to the official documents, after the global installation of Yapi CLI and mongodb, the terminal executes Yapi server, and the browser enters 127.0.0.1:9090 to open the deployment page

After filling in the basic information, click Start deployment, wait for a period of time, the problem appears

node server/install.js

Error:internal/modules/cjs/loader.js:584
   throw err;

Errpr:Cannot find module 'nodemailer'
  at Function.Module_resolveFileName(.........)
  at Function.Module_resolveFileName(.........)
  ........

   

The reason for the error is probably the lack of nodemailer module, so I tried to install the module globally. After the installation, I still reported the same error. In this way, I kept looking for the error. I deleted the project and started over again. After repeated tossing and tossing, I was about to re install the system. After one afternoon’s tossing and tossing, I finally found a solution

2. Solutions

Due to the problem of MAC permission, Yapi is initialized according to the official document writing method, and finally there is no write permission in NPM, resulting in the loss of packets

Modify the “Yapi server” as

sudo yapi server

Then the project is deployed again and the problem is solved
