String hsql=" from Organization porg left join fetch porg.childern as corg ";
List<Organization> results=super.getSession().createQuery(hsql).setCacheable(true).list();
當沒有配置二級緩存，只配置查詢緩存是
第一次的sql爲
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爲
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=? 但當配置上二級緩存，不配置查詢緩存的話。則第二次點擊仍然會發出查詢語句
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 但當配置了二級緩存，再配上查詢緩存時。
第一次爲
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 則直接從內存中獲取了。
