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 AbstractPaging

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 object

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: AbstractPaging

处理分页参数

Specified by:

processPageParameter in class AbstractPaging

Parameters:

ms - MappedStatement

paramMap - Map

page - Page

boundSql - BoundSql

pageKey - CacheKey

Returns:

结果

getPageSql

public String getPageSql(String sql,
 Page page,
 org.apache.ibatis.cache.CacheKey pageKey)

Description copied from class: AbstractPaging

单独处理分页部分

Specified by:

getPageSql in class AbstractPaging

Parameters:

sql - sql

page - Page

pageKey - CacheKey

Returns:

the string

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，Pager转换SQL时报错with(nolock)不识别的问题， 重写父类AbstractPaging.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 AbstractPaging

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 object

setProperties

public void setProperties(Properties properties)

Description copied from interface: Dialect

设置参数

Specified by:

setProperties in interface Dialect

Overrides:

setProperties in class AbstractPaging

Parameters:

properties - 插件属性
