1. MybatisAdvUtil

 

1. 1. 根据session得到所有配置

 

SqlSession conn = MybatisUtil.getConn();

// Configuration Configuration1 = checkSqlValds(conn);

Configuration Configuration1=conn.getConfiguration();

 

1. 1. Configuration1.getMappedStatement(sttID)
   2. 根据语句id得到sql

 

private static String getSqlBoundDefine(SqlSession conn, String sttID)  {

 

Configuration Configuration1 = conn.getConfiguration();

// Configuration1.addLoadedResource(resource);

 

// Configuration1.

MappedStatement MappedStaement1 = Configuration1.getMappedStatement(sttID);

DynamicSqlSource DynamicSqlSource1 = (DynamicSqlSource) MappedStaement1.getSqlSource();

// DynamicSqlSource1.

String fldname = "rootSqlNode";

SqlNode SqlNode1 = (SqlNode) getFldValRE(DynamicSqlSource1, "rootSqlNode");

MixedSqlNode MixedSqlNode1 = (MixedSqlNode) SqlNode1;

List li = (List) getFldValRE(MixedSqlNode1, "contents");

// StaticTextSqlNode <String,TextSqlNode> <TextSqlNode>

 

Object r = li.stream().reduce("", (s, o) -> {

 

String string = "";

try {

string = getFldVal(o, "text").toString();

} catch (NoSuchFieldException | IllegalAccessException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return s + string;

});

return r.toString();

}

 

1. 1. 得到解析后的sql

 

private static String getSqlBound(SqlSession conn,String sttID) {

Configuration Configuration1=conn.getConfiguration();

 

MappedStatement MappedStaement1= Configuration1.getMappedStatement(sttID);

String sqlBound = MappedStaement1.getSqlSource().getBoundSql(null).getSql();

return sqlBound;

}

 

1. 1. getXmlPath

// mapper/ veDao.xml

private static String getXmlPath(SqlSession conn, String sttID) throws Exception {

Configuration Configuration1 = conn.getConfiguration();

// Configuration1.addLoadedResource(resource);

 

// Configuration1.

MappedStatement MappedStaement1 = Configuration1.getMappedStatement(sttID);

 

// DynamicSqlSource1

return MappedStaement1.getResource();

// String sqlBound = MappedStaement1.getSqlSource().getBoundSql(null).getSql();

// return sqlBound;

}
