項目中需要將HR模塊中的表數(shù)據(jù)同步到Java系統(tǒng)中，向外圍系統(tǒng)提供分發(fā)與查詢服務，涉及到的表有兩百多張，字段好幾千上萬個，如果手工一張張這些ABAP表在Java系統(tǒng)數(shù)據(jù)庫中創(chuàng)建一遍的話，工作量將非常大，而且容易出錯。
該ABAP代碼就是將需要的表轉(zhuǎn)換成Java中的實體Bean，然后就可以使用Hibernate之類的持久化框架來自動生成表了。
ABAP代碼沒有重構(gòu)過，寫得有點亂......將就著看吧

上面是PA0000這個表所生成的實體Bean，每張會生成兩個類，PK結(jié)尾的是主鍵，另一個是非主鍵Bean。另外，除了ABAP表的字段外，可能還需擴展幾個字段，這些擴展字段可以放在?BaseEntity?父類里：package?com.xxx;import?java.io.Serializable;import?javax.persistence.Column;import?javax.persistence.MappedSuperclass;import?javax.persistence.Transient;@MappedSuperclasspublic?class?BaseEntity?implements?Serializable?{????@Transient????private?static?final?long?serialVersionUID?=?1L;????@Transient????private?String?module;//?表所屬模塊????@Transient????private?String?tableName;//?表名????private?String?insertTime;//?數(shù)據(jù)插入時間????private?String?lastUpdateTime;//?數(shù)據(jù)最后一次更新時間????private?String?deleteFlg;//?是否被刪除了????@Column(length?=?14,?name?=?"INSERT_TIME",?updatable?=?false)????public?String?getInsertTime()?{????????return?insertTime;????}????public?void?setInsertTime(String?insertTime)?{????????this.insertTime?=?insertTime;????}????@Column(length?=?14,?name?=?"LAST_UPDATE_TIME")????public?String?getLastUpdateTime()?{????????return?lastUpdateTime;????}????public?void?setLastUpdateTime(String?lastUpdateTime)?{????????this.lastUpdateTime?=?lastUpdateTime;????}????@Column(length?=?1,?name?=?"DELETE_FLG")????public?String?getDeleteFlg()?{????????return?deleteFlg;????}????public?void?setDeleteFlg(String?deleteFlg)?{????????this.deleteFlg?=?deleteFlg;????}????@Transient????public?String?getModule()?{????????return?module;????}????public?void?setModule(String?module)?{????????this.module?=?module;????}????@Transient????public?String?getTableName()?{????????return?tableName;????}????public?void?setTableName(String?tableName)?{????????this.tableName?=?tableName;????}}
生成這些實體Bean類后，然后使用Hibernate持久化框架就可以自動生成表了，這里不再演示，做過Java Web開發(fā)的都知道，Easy.....不過要注意的是，Hibernate根據(jù)實體類生成表時，發(fā)現(xiàn)字段順序與實體Bean中定義的字段順序不一樣，這也就與ABAP表字段順序不一樣了，這是Hibernate的問題，可以修改Hibernate里相應Jar包里這個類，并將它替換掉即可：注意Hibernate版本是4.3.8的，下面是經(jīng)過修改后的類，編譯后替換原Jar包中相應的類即可：/*?*?Hibernate,?Relational?Persistence?for?Idiomatic?Java?*?*?Copyright?(c)?2010,?Red?Hat?Inc.?or?third-party?contributors?as?*?indicated?by?the?@author?tags?or?express?copyright?attribution?*?statements?applied?by?the?authors.??All?third-party?contributions?are?*?distributed?under?license?by?Red?Hat?Inc.?*?*?This?copyrighted?material?is?made?available?to?anyone?wishing?to?use,?modify,?*?copy,?or?redistribute?it?subject?to?the?terms?and?conditions?of?the?GNU?*?Lesser?General?Public?License,?as?published?by?the?Free?Software?Foundation.?*?*?This?program?is?distributed?in?the?hope?that?it?will?be?useful,?*?but?WITHOUT?ANY?WARRANTY;?without?even?the?implied?warranty?of?MERCHANTABILITY?*?or?FITNESS?FOR?A?PARTICULAR?PURPOSE.??See?the?GNU?Lesser?General?Public?License?*?for?more?details.?*?*?You?should?have?received?a?copy?of?the?GNU?Lesser?General?Public?License?*?along?with?this?distribution;?if?not,?write?to:?*?Free?Software?Foundation,?Inc.?*?51?Franklin?Street,?Fifth?Floor?*?Boston,?MA??02110-1301??USA?*///?$Id$package?org.hibernate.cfg;import?java.util.Collection;import?java.util.Collections;import?java.util.Iterator;import?java.util.LinkedHashMap;import?java.util.LinkedList;import?java.util.List;import?java.util.Map;import?javax.persistence.Access;import?javax.persistence.ManyToMany;import?javax.persistence.ManyToOne;import?javax.persistence.OneToMany;import?javax.persistence.OneToOne;import?javax.persistence.Transient;import?org.hibernate.AnnotationException;import?org.hibernate.MappingException;import?org.hibernate.annotations.ManyToAny;import?org.hibernate.annotations.Target;import?org.hibernate.annotations.Type;import?org.hibernate.annotations.common.reflection.XClass;import?org.hibernate.annotations.common.reflection.XProperty;import?org.hibernate.internal.CoreMessageLogger;import?org.hibernate.internal.util.StringHelper;import?org.jboss.logging.Logger;/**?*?A?helper?class?to?keep?the?{@code?XProperty}s?of?a?class?ordered?by?access?*?type.?*??*?@author?Hardy?Ferentschik?*/class?PropertyContainer?{????static?{????????System.setProperty("jboss.i18n.generate-proxies",?"true");????}????private?static?final?CoreMessageLogger?LOG?=?Logger.getMessageLogger(CoreMessageLogger.class,????????????PropertyContainer.class.getName());????private?final?AccessType?explicitClassDefinedAccessType;????/**?????*?Constains?the?properties?which?must?be?returned?in?case?the?class?is?accessed?????*?via?{@code?AccessType.FIELD}.?Note,?this?does?not?mean?that?all?????*?{@code?XProperty}s?in?this?map?are?fields.?Due?to?JPA?access?rules?single?????*?properties?can?have?different?access?type?than?the?overall?class?access?type.?????*/????private?final?LinkedHashMap<String,?XProperty>?fieldAccessMap;????/**?????*?Constains?the?properties?which?must?be?returned?in?case?the?class?is?accessed?????*?via?{@code?AccessType.Property}.?Note,?this?does?not?mean?that?all?????*?{@code?XProperty}s?in?this?map?are?properties/methods.?Due?to?JPA?access?????*?rules?single?properties?can?have?different?access?type?than?the?overall?class?????*?access?type.?????*/????private?final?LinkedHashMap<String,?XProperty>?propertyAccessMap;????private?static?LinkedHashMap<String,?XProperty>?fieldAccessMapBase;????private?static?LinkedHashMap<String,?XProperty>?propertyAccessMapBase;????/**?????*?The?class?for?which?this?container?is?created.?????*/????private?final?XClass?xClass;????private?final?XClass?entityAtStake;????PropertyContainer(XClass?clazz,?XClass?entityAtStake)?{????????this.xClass?=?clazz;????????this.entityAtStake?=?entityAtStake;????????explicitClassDefinedAccessType?=?determineClassDefinedAccessStrategy();????????//?first?add?all?properties?to?field?and?property?map????????if?(xClass.getName().toLowerCase().endsWith("baseentity"))?{????????????if?(fieldAccessMapBase?==?null)?{????????????????fieldAccessMapBase?=?initProperties(AccessType.FIELD);????????????????propertyAccessMapBase?=?initProperties(AccessType.PROPERTY);????????????}????????????fieldAccessMap?=?new?LinkedHashMap<String,?XProperty>();????????????propertyAccessMap?=?new?LinkedHashMap<String,?XProperty>();????????}?else?{????????????fieldAccessMap?=?initProperties(AccessType.FIELD);????????????propertyAccessMap?=?initProperties(AccessType.PROPERTY);????????}????????considerExplicitFieldAndPropertyAccess();????}????public?XClass?getEntityAtStake()?{????????return?entityAtStake;????}????public?XClass?getDeclaringClass()?{????????return?xClass;????}????public?AccessType?getExplicitAccessStrategy()?{????????return?explicitClassDefinedAccessType;????}????public?boolean?hasExplicitAccessStrategy()?{????????return?!explicitClassDefinedAccessType.equals(AccessType.DEFAULT);????}????public?Collection<XProperty>?getProperties(AccessType?accessType)?{????????assertTypesAreResolvable
