方法详细资料

intercept

public Object intercept(org.apache.ibatis.plugin.Invocation invocation)
                 throws Throwable

指定者:

intercept 在接口中 org.apache.ibatis.plugin.Interceptor

抛出:

Throwable

newMappedStatement

private org.apache.ibatis.mapping.MappedStatement newMappedStatement(org.apache.ibatis.mapping.MappedStatement ms,
                                                                     SupportJoinWrapper joinLambdaWrapper,
                                                                     Class<?> classType)

构建新的MappedStatement

newResultMap

private org.apache.ibatis.mapping.ResultMap newResultMap(org.apache.ibatis.mapping.MappedStatement ms,
                                                         SupportJoinWrapper joinLambdaWrapper,
                                                         Class<?> classType)

构建resultMap

addResultMap

private void addResultMap(org.apache.ibatis.session.Configuration configuration,
                          org.apache.ibatis.mapping.ResultMap resultMap,
                          String id)

buildResultMapping

private List<org.apache.ibatis.mapping.ResultMapping> buildResultMapping(org.apache.ibatis.session.Configuration configuration,
                                                                         List<FieldMapping> fieldMappings,
                                                                         Class<?> clz)

构建结果集映射

参数:

clz - mapper方法返回的类型
