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...
