String hsql=" from Organization porg left join fetch porg.childern as corg ";
List<Organization> results=super.getSession().createQuery(hsql).setCacheable(true).list();
当没有配置二级缓存，只配置查询缓存是
第一次的sql为
select organizati0_.ID as ID0_0_, childern1_.ID as ID0_1_, organizati0_.ORGANIZATION_NAME as ORGANIZA2_0_0_, organizati0_.ORGANIZATION_SN as ORGANIZA3_0_0_, organizati0_.DESCRIPTION as DESCRIPT4_0_0_, organizati0_.PID as PID0_0_, organizati0_.ORGANIZATION_TEL as ORGANIZA6_0_0_, organizati0_.ORDER_NUM as ORDER7_0_0_, organizati0_.PERSON_ID as PERSON8_0_0_, childern1_.ORGANIZATION_NAME as ORGANIZA2_0_1_, childern1_.ORGANIZATION_SN as ORGANIZA3_0_1_, childern1_.DESCRIPTION as DESCRIPT4_0_1_, childern1_.PID as PID0_1_, childern1_.ORGANIZATION_TEL as ORGANIZA6_0_1_, childern1_.ORDER_NUM as ORDER7_0_1_, childern1_.PERSON_ID as PERSON8_0_1_, childern1_.PID as PID0__, childern1_.ID as ID0__ from g_organization organizati0_ left outer join g_organization childern1_ on organizati0_.ID=childern1_.PID 第二次sql为
select organizati0_.ID as ID0_1_, organizati0_.ORGANIZATION_NAME as ORGANIZA2_0_1_, organizati0_.ORGANIZATION_SN as ORGANIZA3_0_1_, organizati0_.DESCRIPTION as DESCRIPT4_0_1_, organizati0_.PID as PID0_1_, organizati0_.ORGANIZATION_TEL as ORGANIZA6_0_1_, organizati0_.ORDER_NUM as ORDER7_0_1_, organizati0_.PERSON_ID as PERSON8_0_1_, childern1_.PID as PID3_, childern1_.ID as ID3_, childern1_.ID as ID0_0_, childern1_.ORGANIZATION_NAME as ORGANIZA2_0_0_, childern1_.ORGANIZATION_SN as ORGANIZA3_0_0_, childern1_.DESCRIPTION as DESCRIPT4_0_0_, childern1_.PID as PID0_0_, childern1_.ORGANIZATION_TEL as ORGANIZA6_0_0_, childern1_.ORDER_NUM as ORDER7_0_0_, childern1_.PERSON_ID as PERSON8_0_0_ from g_organization organizati0_ left outer join g_organization childern1_ on organizati0_.ID=childern1_.PID where organizati0_.ID=? Hibernate: select organizati0_.ID as ID0_1_, organizati0_.ORGANIZATION_NAME as ORGANIZA2_0_1_, organizati0_.ORGANIZATION_SN as ORGANIZA3_0_1_, organizati0_.DESCRIPTION as DESCRIPT4_0_1_, organizati0_.PID as PID0_1_, organizati0_.ORGANIZATION_TEL as ORGANIZA6_0_1_, organizati0_.ORDER_NUM as ORDER7_0_1_, organizati0_.PERSON_ID as PERSON8_0_1_, childern1_.PID as PID3_, childern1_.ID as ID3_, childern1_.ID as ID0_0_, childern1_.ORGANIZATION_NAME as ORGANIZA2_0_0_, childern1_.ORGANIZATION_SN as ORGANIZA3_0_0_, childern1_.DESCRIPTION as DESCRIPT4_0_0_, childern1_.PID as PID0_0_, childern1_.ORGANIZATION_TEL as ORGANIZA6_0_0_, childern1_.ORDER_NUM as ORDER7_0_0_, childern1_.PERSON_ID as PERSON8_0_0_ from g_organization organizati0_ left outer join g_organization childern1_ on organizati0_.ID=childern1_.PID where organizati0_.ID=? 但当配置上二级缓存，不配置查询缓存的话。则第二次点击仍然会发出查询语句
select organizati0_.ID as ID0_0_, childern1_.ID as ID0_1_, organizati0_.ORGANIZATION_NAME as ORGANIZA2_0_0_, organizati0_.ORGANIZATION_SN as ORGANIZA3_0_0_, organizati0_.DESCRIPTION as DESCRIPT4_0_0_, organizati0_.PID as PID0_0_, organizati0_.ORGANIZATION_TEL as ORGANIZA6_0_0_, organizati0_.ORDER_NUM as ORDER7_0_0_, organizati0_.PERSON_ID as PERSON8_0_0_, childern1_.ORGANIZATION_NAME as ORGANIZA2_0_1_, childern1_.ORGANIZATION_SN as ORGANIZA3_0_1_, childern1_.DESCRIPTION as DESCRIPT4_0_1_, childern1_.PID as PID0_1_, childern1_.ORGANIZATION_TEL as ORGANIZA6_0_1_, childern1_.ORDER_NUM as ORDER7_0_1_, childern1_.PERSON_ID as PERSON8_0_1_, childern1_.PID as PID0__, childern1_.ID as ID0__ from g_organization organizati0_ left outer join g_organization childern1_ on organizati0_.ID=childern1_.PID 但当配置了二级缓存，再配上查询缓存时。
第一次为
select organizati0_.ID as ID0_0_, childern1_.ID as ID0_1_, organizati0_.ORGANIZATION_NAME as ORGANIZA2_0_0_, organizati0_.ORGANIZATION_SN as ORGANIZA3_0_0_, organizati0_.DESCRIPTION as DESCRIPT4_0_0_, organizati0_.PID as PID0_0_, organizati0_.ORGANIZATION_TEL as ORGANIZA6_0_0_, organizati0_.ORDER_NUM as ORDER7_0_0_, organizati0_.PERSON_ID as PERSON8_0_0_, childern1_.ORGANIZATION_NAME as ORGANIZA2_0_1_, childern1_.ORGANIZATION_SN as ORGANIZA3_0_1_, childern1_.DESCRIPTION as DESCRIPT4_0_1_, childern1_.PID as PID0_1_, childern1_.ORGANIZATION_TEL as ORGANIZA6_0_1_, childern1_.ORDER_NUM as ORDER7_0_1_, childern1_.PERSON_ID as PERSON8_0_1_, childern1_.PID as PID0__, childern1_.ID as ID0__ from g_organization organizati0_ left outer join g_organization childern1_ on organizati0_.ID=childern1_.PID 而第二次 则直接从内存中获取了。
