添加技能类别类和数据库

zangcf

1，首先建立domain的SkillClass类
package com.shopping.foundation.domain;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Lob;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;

@Cache(usage=CacheConcurrencyStrategy.READ_WRITE)
@Entity
@Table(name="workshop_worktype")
public class SkillClass {
        private String name;

        public String getName() {
                return name;
        }

        public void setName(String name) {
                this.name = name;
        }

        public String getComment() {
                return comment;
        }

        public void setComment(String comment) {
                this.comment = comment;
        }

        public int getSequence() {
                return sequence;
        }

        public void setSequence(int sequence) {
                this.sequence = sequence;
        }

        public int getLevel() {
                return level;
        }

        public void setLevel(int level) {
                this.level = level;
        }

        public SkillClass getParent() {
                return parent;
        }

        public void setParent(SkillClass parent) {
                this.parent = parent;
        }

        @Lob
        @Column(columnDefinition="LongText")
        private String comment;

           @Column(columnDefinition="int default 0")
           private int sequence;
         
           @Column(columnDefinition="int default 0")
           private int level;

           @ManyToOne(fetch=FetchType.LAZY)
           private SkillClass parent;

}

2，建立SkillClassDAO：
package com.shopping.foundation.dao;

import org.springframework.stereotype.Repository;

import com.shopping.core.base.GenericDAO;
import com.shopping.foundation.domain.SkillClass;

@Repository("skillClassDAO")
public class SkillClassDAO  extends GenericDAO<SkillClass>{

}

zangcf

3，建立ISkillClass接口：
package com.shopping.foundation.service;

import java.io.Serializable;
import java.util.List;
import java.util.Map;

import com.shopping.core.query.support.IPageList;
import com.shopping.core.query.support.IQueryObject;
import com.shopping.foundation.domain.SkillClass;

public  abstract interface ISkillClassService {
          public abstract boolean save(SkillClass paramSkillClass);

          public abstract SkillClass getObjById(Long paramLong);

          public abstract boolean delete(Long paramLong);

          public abstract boolean batchDelete(List<Serializable> paramList);

          public abstract IPageList list(IQueryObject paramIQueryObject);

          public abstract boolean update(SkillClass paramSkillClass);

          public abstract List<SkillClass> query(String paramString, Map paramMap, int paramInt1, int paramInt2);

          public abstract SkillClass getObjByProperty(String paramString, Object paramObject);

}

zangcf

4，建立SkillClassServiceImpl类：
package com.shopping.foundation.service.impl;

import java.io.Serializable;
import java.util.List;
import java.util.Map;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.shopping.core.dao.IGenericDAO;
import com.shopping.core.query.GenericPageList;
import com.shopping.core.query.PageObject;
import com.shopping.core.query.support.IPageList;
import com.shopping.core.query.support.IQueryObject;
import com.shopping.foundation.domain.SkillClass;
import com.shopping.foundation.service.ISkillClassService;

@Service
@Transactional
public class SkillClassServiceImpl implements ISkillClassService{
           @Resource(name="skillClassDao")
           private IGenericDAO<SkillClass> skillClassDao;
          
           public boolean save(SkillClass skillClass)
           {
             try
             {
               this.skillClassDao.save(skillClass);
               return true;
             } catch (Exception e) {
               e.printStackTrace();
             }return false;
           }

           public SkillClass getObjById(Long id)
           {
                   SkillClass skillClass = (SkillClass)this.skillClassDao.get(id);
             if (skillClass != null) {
               return skillClass;
             }
             return null;
           }
         
           public boolean delete(Long id) {
             try {
               this.skillClassDao.remove(id);
               return true;
             } catch (Exception e) {
               e.printStackTrace();
             }return false;
           }
         
           public boolean batchDelete(List<Serializable> skillClassIds)
           {
             for (Serializable id : skillClassIds) {
               delete((Long)id);
             }
             return true;
           }
         
           public IPageList list(IQueryObject properties) {
             if (properties == null) {
               return null;
             }
             String query = properties.getQuery();
             Map params = properties.getParameters();
             GenericPageList pList = new GenericPageList(SkillClass.class, query,
               params, this.skillClassDao);
             if (properties != null) {
               PageObject pageObj = properties.getPageObj();
               if (pageObj != null)
                 pList.doList(pageObj.getCurrentPage() == null ? 0 : pageObj
                   .getCurrentPage().intValue(), pageObj.getPageSize() == null ? 0 :
                   pageObj.getPageSize().intValue());
             } else {
               pList.doList(0, -1);
             }return pList;
           }
         
           public boolean update(SkillClass skillClass) {
             try {
               this.skillClassDao.update(skillClass);
               return true;
             } catch (Exception e) {
               e.printStackTrace();
             }return false;
           }
         
           public List<SkillClass> query(String query, Map params, int begin, int max) {
             return this.skillClassDao.query(query, params, begin, max);
           }
         
           public SkillClass getObjByProperty(String propertyName, Object value)
           {
             return (SkillClass)this.skillClassDao.getBy(propertyName, value);
           }

}

zangcf

5，建立SkillClassQueryObject：
package com.shopping.foundation.domain.query;

import org.springframework.web.servlet.ModelAndView;

import com.shopping.core.query.QueryObject;

public class SkillClassQueryObject  extends QueryObject{
           public SkillClassQueryObject(String currentPage, ModelAndView mv, String orderBy, String orderType)
           {
             super(currentPage, mv, orderBy, orderType);
           }
         
           public SkillClassQueryObject()
           {
           }

}

添加失败了，还要再重头来一次。不知道是什么原因出错：

上面的错误是由于代码当中一点手误导致
             GenericPageList pList = new GenericPageList(S.class, query,
               params, this.skillClassDao);
