Liferay的服務構建表自動遞增在每個部署

Question

在Liferay中我有如下一個實體：

<entity name="Foo" local-service="true" remote-service="true"> 

     <!-- PK fields --> 

     <column name="fooId" type="long" primary="true" /> 

     <!-- Group instance --> 

     <column name="groupId" type="long" /> 

     <!-- Audit fields --> 

     <column name="companyId" type="long" /> 
     <column name="userId" type="long" /> 
     <column name="userName" type="String" /> 
     <column name="createDate" type="Date" /> 
     <column name="modifiedDate" type="Date" /> 

     <!-- Other fields --> 

     <column name="field1" type="String" /> 
     <column name="field2" type="boolean" /> 
     <column name="field3" type="int" /> 
     <column name="field4" type="Date" /> 
     <column name="field5" type="String" /> 

     <!-- Order --> 

     <order by="asc"> 
      <order-column name="field1" /> 
     </order> 

     <!-- Finder methods --> 

     <finder name="Field2" return-type="Collection"> 
      <finder-column name="field2" /> 
     </finder> 
    </entity> 

當我改變portlet的代碼。在每次部署時，其主鍵增加100. 因此無論如何只能將其自動增量設置爲1。而且每次部署時不得增加100。

Answer 1

選項＃1

在您的主鍵列添加此id-type="increment"

即

<column name="fooId" type="long" primary="true" id-type="increment" /> 

缺點： 這將打破集羣環境

選項＃2

在portal-ext.properties添加此

# 
# Set the number of increments between database updates to the Counter 
# table. Set this value to a higher number for better performance. 
# 
counter.increment=1 //by default it is 100 

缺點：這會影響你的表現。
