新写了一个接口,期望根据不同的参数来给数据库中不同的字段进行传值。这里使用了内部静态枚举类的方式进行传值,在写mybatis动态sql时,如果是普通对象,一般使用
Mapper接口
public class SLineSboxesQueryParam {
private QueryMethod queryMethod;//查询方式的枚举内部类
private List idList;
private LocalDateTime startTime;
private LocalDateTime endTime;
public SLineSboxesQueryParam() {
}
//省略getter setter方法
public void checkHasNecessaryFields() {
if (this.queryMethod == null) {
throw new ApiException(ResultCode.PARAMS_ERROR, "queryMethod is missing");
} else if (CollectionUtils.isEmpty(this.idList)) {
throw new ApiException(ResultCode.PARAMS_ERROR, "idList is missing");
} else if (this.startTime == null) {
throw new ApiException(ResultCode.PARAMS_ERROR, "startTime is missing");
} else if (this.endTime == null) {
throw new ApiException(ResultCode.PARAMS_ERROR,"endTime is missing");
}
}
//定义查询方式
public static enum QueryMethod { //此处定义了内部枚举类
BySpecIdList, BySLineIdList, ByVplIdList;
QueryMethod() {
}
}
}
mappers.xml配置
//resultMap
//sql
