mybatisplus alleq

MyBatis-Plus is an enhanced version of MyBatis, a popular Java-based persistence framework. It provides additional features and utilities to simplify the development process when working with MyBatis.

The `alleq` method in MyBatis-Plus is a convenient method provided by the framework for performing batch equal condition queries. It allows you to query records that match multiple equality conditions on the specified fields.

Here is an example of using `alleq` with MyBatis-Plus:

// Assuming you have a User entity with 'name' and 'age' properties

// Create a wrapper object
QueryWrapper<User> queryWrapper = new QueryWrapper<>();

// Set the equality conditions
Map<String, Object> conditionMap = new HashMap<>();
conditionMap.put("name", "John");
conditionMap.put("age", 25);
queryWrapper.allEq(conditionMap);

// Perform the query
List<User> userList = userMapper.selectList(queryWrapper);

In this example, `alleq` is used to create an equality condition query for all fields specified in the `conditionMap`. The resulting `userList` will contain all users with the name "John" and age 25.

Note that you need to have MyBatis-Plus properly configured in your project, including setting up the entity mappings and the necessary dependencies.
