类 EasyCriteria

java.lang.Object

cn.easyproject.easycommons.commondao.util.EasyCriteria

public abstract class EasyCriteria
extends Object

按条件查询抽象父类（可以结合分页PageBean使用） SysUserCriteria Demo:

 public class SysUserCriteria extends EasyCriteria implements java.io.Serializable {
        // 1. Criteria field
        private String name;
        private String realName;
        private Integer status; // 0 is ON; 1 is OFF; 2 is REMOVED
 
        // 2. Constructor
        public SysUserCriteria() {
        }
 
        public SysUserCriteria(String name, String realName, Integer status) {
                super();
                this.name = name;
                this.realName = realName;
                this.status = status;
        }
 
        // 3. Condition genertator abstract method implements
        public String getCondition() {
                values.clear(); // **Must clear old values**
                StringBuffer condition = new StringBuffer();
                if (StringUtils.isNotNullAndEmpty(this.getName())) {
                        condition.append(" and name like ?");
                        values.add("%" + this.getName() + "%");
                }
                if (StringUtils.isNotNullAndEmpty(this.getRealName())) {
                        condition.append(" and realName like ?");
                        values.add("%" + this.getRealName() + "%");
                }
                if (StringUtils.isNotNullAndEmpty(this.getStatus())) {
                        condition.append(" and status=?");
                        values.add(this.getStatus());
                }
                return condition.toString();
        }
 
        // 4. Setters&Getters...
 
 }
