Recently, spring4.x was used to integrate Jackson ------> java. lang. ClassNotFoundException :, Recently, Jackson was integrated with spring4.x, and the results were inexplicably reported.

There are a lot of repeated code in MybatisFirst. The code is simplified this time: There are two methods to develop D

Mapper interface development method only requires programmers to write the Mapper interface (equivalent to DAO interface), the MyBatis framework creates an interface based on the interface definition of the dynamic proxy object, the proxy object's method body with the upper DAO interface implementation class method.Mapper interface development is subject to the following specifications:1. The namespace in t

The previous post summarizes some of the drawbacks of MyBatis's approach to using primitive DAO, and we certainly won't use it, so how do we develop DAO in MyBatis? As described in title, this blog post mainly summarizes the steps to develop DAO using the Mapper proxy method.When developing DAO using the Mapper proxy method, programmers only need to do two things: Need to write Mapper.xml map

Mybatis-spring allows you to inject the mapper into the service bean. When using the Mapper, call the mapper just as you would call DAO, but at this point you do not need to encode any DAO implementations because MyBatis will do it for you.With the injected mapper, your code will not appear to have any mybatis-spring d
