getCountSql

public String getCountSql(org.apache.ibatis.mapping.MappedStatement ms,
                          org.apache.ibatis.mapping.BoundSql boundSql,
                          Object parameterObject,
                          org.apache.ibatis.session.RowBounds rowBounds,
                          org.apache.ibatis.cache.CacheKey countKey)

Description copied from interface: Dialect

生成 count 查询 sql

Specified by:

getCountSql in interface Dialect

Overrides:

getCountSql in class AbstractHelperDialect

Parameters:

ms - MappedStatement

boundSql - 绑定 SQL 对象

parameterObject - 方法参数

rowBounds - 分页参数

countKey - count 缓存 key

Returns:

the string

processPageParameter

public Object processPageParameter(org.apache.ibatis.mapping.MappedStatement ms,
                                   Map<String,Object> paramMap,
                                   Page page,
                                   org.apache.ibatis.mapping.BoundSql boundSql,
                                   org.apache.ibatis.cache.CacheKey pageKey)

Description copied from class: AbstractHelperDialect

处理分页参数

Specified by:

processPageParameter in class AbstractHelperDialect

Parameters:

ms - MappedStatement

paramMap - Map

page - Page

boundSql - BoundSql

pageKey - CacheKey

Returns:

结果

getPageSql

public String getPageSql(org.apache.ibatis.mapping.MappedStatement ms,
                         org.apache.ibatis.mapping.BoundSql boundSql,
                         Object parameterObject,
                         org.apache.ibatis.session.RowBounds rowBounds,
                         org.apache.ibatis.cache.CacheKey pageKey)

分页查询，pageHelper转换SQL时报错with(nolock)不识别的问题， 重写父类AbstractHelperDialect.getPageSql转换出错的方法。 1. this.replaceSql.replace(sql);先转换成假的表名 2. 然后进行SQL转换 3. this.replaceSql.restore(sql);最后再恢复成真的with(nolock)

Specified by:

getPageSql in interface Dialect

Overrides:

getPageSql in class AbstractHelperDialect

Parameters:

ms - MappedStatement

boundSql - 绑定 SQL 对象

parameterObject - 方法参数

rowBounds - 分页参数

pageKey - 分页缓存 key

Returns:

the string
