程序包 com.baomidou.mybatisplus.core.conditions

类 AbstractLambdaWrapper<T,Children extends AbstractLambdaWrapper<T,Children>>

java.lang.Object

com.baomidou.mybatisplus.core.conditions.Wrapper<T>

com.baomidou.mybatisplus.core.conditions.AbstractWrapper<T,SFunction<T,?>,Children>

com.baomidou.mybatisplus.core.conditions.AbstractLambdaWrapper<T,Children>

所有已实现的接口:

Compare<Children,SFunction<T,?>>, Func<Children,SFunction<T,?>>, Join<Children>, Nested<Children,Children>, ISqlSegment, java.io.Serializable

直接已知子类:

LambdaQueryWrapper, LambdaUpdateWrapper

public abstract class AbstractLambdaWrapper<T,Children extends AbstractLambdaWrapper<T,Children>>
extends AbstractWrapper<T,SFunction<T,?>,Children>

Lambda 语法使用 Wrapper

统一处理解析 lambda 获取 column

从以下版本开始:

AbstractLambdaWrapper

public AbstractLambdaWrapper()

方法详细资料

columnsToString

@SafeVarargs
protected final java.lang.String columnsToString(SFunction<T,?>... columns)

从类复制的说明: AbstractWrapper

获取 columnNames

覆盖:

columnsToString 在类中 AbstractWrapper<T,SFunction<T,?>,Children extends AbstractLambdaWrapper<T,Children>>

columnsToString

@SafeVarargs
protected final java.lang.String columnsToString(boolean onlyColumn,
                                                 SFunction<T,?>... columns)

columnsToString

protected final java.lang.String columnsToString(boolean onlyColumn,
                                                 java.util.List<SFunction<T,?>> columns)

columnToString

protected java.lang.String columnToString(SFunction<T,?> column)

从类复制的说明: AbstractWrapper

获取 columnName

覆盖:

columnToString 在类中 AbstractWrapper<T,SFunction<T,?>,Children extends AbstractLambdaWrapper<T,Children>>

columnToString

protected java.lang.String columnToString(SFunction<T,?> column,
                                          boolean onlyColumn)

getColumnCache

protected ColumnCache getColumnCache(SFunction<T,?> column)

获取 SerializedLambda 对应的列信息，从 lambda 表达式中推测实体类

如果获取不到列信息，那么本次条件组装将会失败

返回:

列

抛出:

MybatisPlusException - 获取不到列信息时抛出异常
