selectAutoIncludeTable
3.1.51+默认使用selectAutoInclude如果存在数据库实体(@Table)的实体那么就会默认报错可以选择警告或者忽略
notEmptyAll
3.1.51+支持all函数并且要求集合不为空
List<SysUser> list = easyEntityQuery.queryable(SysUser.class)
.where(user -> {
user.bankCards().where(bc -> bc.type().eq("储蓄卡")).notEmptyAll(bc -> bc.code().startsWith("33123"));
}).toList();include2
移除includeBy使用插件提示icnlude2(因为是include内部有两参数),用于处理复杂多链路结构化include
List<SchoolClass> list = easyEntityQuery.queryable(SchoolClass.class)
.include((c,s)->{
c.query(s.schoolTeachers().flatElement().schoolClasses()).where(a -> a.name().like("123"));
c.query(s.schoolStudents().flatElement().schoolClass()).where(x -> x.schoolStudents().flatElement().name().eq("123"));
c.query(s.schoolStudents()).where(x -> x.name().ne("123"));
})
.toList();include统一
3.1.49+eq对所有的include进行了统一不需要再区分include还是includes
子查询all函数
3.1.46+eq添加了子查询all函数
LocalDateTime time = LocalDateTime.of(2020, 1, 1, 0, 0, 0);
List<SysUser> list = easyEntityQuery.queryable(SysUser.class)
.where(user -> {
user.bankCards().where(bc -> bc.type().eq("储蓄卡")).all(bc -> bc.openTime().le(time));
}).toList();该表达式是查询用户并且要求用户的所有储蓄卡都是2020-01-01之前的
说明!!!
all函数内的断言是一个独立的断言,他是对all函数之前的表达式进行断言,并不是将all之前的where和all进行简单的组合，是一种非常符合语义的表达式(空集合的all断言永远为true)
toResultSet
3.1.43+eq添加了toResultSet方法支持用户自行处理ResultSet框架不做任何处理(不支持include等操作只适合单表)
List<BlogEntity> resultSet = easyEntityQuery.queryable(SysUser.class)
.where(s -> {
s.id().isNotNull();
}).toResultSet(context -> {
ArrayList<BlogEntity> blogEntities = new ArrayList<>();
StreamResultSet streamResultSet = context.getStreamResultSet();
ResultSet resultSetResultSet = streamResultSet.getResultSet();
while (resultSetResultSet.next()) {
BlogEntity blogEntity = new BlogEntity();
blogEntity.setId(resultSetResultSet.getString(1));
blogEntities.add(blogEntity);
}
return blogEntities;
});kotlin中缀
3.1.43+kotlin支持中缀建议插件升级到0.1.67具体查看kotlin相关的eq文档
forEach
3.1.38+支持forEach迭代处理结果,场景:在多次include的时候可能需要根据根节点进行判断是否状态正确,基于性能原因应该先进行判断在进行include,而不是全部include完了后在进行判断
M8SaveA a1 = easyEntityQuery.queryable(M8SaveA.class).whereById("1")
.includeBy(m -> Include.of(
m.m8SaveB().m8SaveC().m8SaveD().asIncludeQueryable()
))
.forEach(item -> {
if (item.getId().equals("1")) {
throw new RuntimeException("123123");
}
}).singleNotNull();
该表达式会先进行断言然后在会进行`include`duckdb查询excel
3.1.33+版本支持duckdb读取excel并且支持隐式操作和join操作
@Data
@EntityProxy
@Table(value = "read_xlsx('./ducktest.xlsx',sheet='Sheet1')", keyword = false)
public class ExcelDuck implements ProxyEntityAvailable<ExcelDuck, ExcelDuckProxy> {
private String id;
private String name;
private Integer age;
/**
*
**/
@Navigate(value = RelationTypeEnum.OneToMany, selfProperty = {ExcelDuckProxy.Fields.id}, targetProperty = {ExcelDuck2Proxy.Fields.uid})
private List<ExcelDuck2> excelDuck2List;
}
@Data
@EntityProxy
@Table(value = "read_xlsx('./ducktest.xlsx',sheet='Sheet2')",keyword = false)
public class ExcelDuck2 implements ProxyEntityAvailable<ExcelDuck2, ExcelDuck2Proxy> {
private String id;
private String uid;
private String name;
private Integer age;
}
List<ExcelDuck> list = easyEntityQuery.queryable(ExcelDuck.class)
.configure(s->s.getBehavior().add(EasyBehaviorEnum.ALL_SUB_QUERY_GROUP_JOIN))
.where(e -> {
e.excelDuck2List().any(s->s.id().eq("2"));
}).toList();
SELECT t."id", t."name", t."age"
FROM read_xlsx('./ducktest.xlsx', sheet = 'Sheet1') t
LEFT JOIN (
SELECT t1."uid" AS "uid", COUNT(1) > 0 AS "__any2__"
FROM read_xlsx('./ducktest.xlsx', sheet = 'Sheet2') t1
WHERE t1."id" = '2'
GROUP BY t1."uid"
) t2
ON t2."uid" = t."id"
WHERE COALESCE(t2."__any2__", false) = true最大(小)列
3.1.32+版本支持同一行里面获取最大列,且默认忽略null
支持GREATEST和LEAST且支持忽略null的则使用该函数,如果不支持或者不支持忽略null的则通过case when或其他方式来支持
List<DamengMyTopic> list = entityQuery.queryable(DamengMyTopic.class)
.where(d -> {
d.expression().maxColumns(d.id(), d.title(), d.title().nullOrDefault(d.id())).eq("123");
}).toList();偏移量函数
3.1.30+版本支持偏移量函数LAG、LEAD、FIRST_VALUE、LAST_VALUE、NTH_VALUE函数支持
easyEntityQuery.queryable(SysBankCard.class)
.orderBy(bank_card -> {
bank_card.openTime().asc();
})
.select(bank_card -> Select.DRAFT.of(
bank_card.type(),
bank_card.type().offset().prev(1),
bank_card.type().offset().firstValue()
)).toList();聚合根保存
3.1.24+版本支持完整的聚合根对象保存,用户可以实现无感聚合根保存对象树链路
springboot或者solon需要在@EasyQueryTrack注解下开启追踪模式才可以非框架下可以手动开启追踪
TrackManager trackManager = easyEntityQuery.getRuntimeContext().getTrackManager();
try {
trackManager.begin();
M8SaveRoot root = new M8SaveRoot();
root.setName("rootname");
root.setCode("rootcode");
M8SaveRootOne rootOne = new M8SaveRootOne();
root.setM8SaveRootOne(rootOne);
try (Transaction transaction = easyEntityQuery.beginTransaction()) {
easyEntityQuery.savable(root).executeCommand();//自动保存M8SaveRoot和M8SaveRootOne，并且关联属性框架会自动处理
transaction.commit();
}
} finally {
trackManager.release();
}groupJoin智能条件
隐式Group，隐式Partition 性能再优化3.0.90将支持groupJoin如果存在单个关联key被外部筛选则会将该筛选条件穿透进子查询内部
目前开启该功能需要自行替换服务
.replaceService(SubQueryExtraPredicateProvider.class, DefaultSubQueryExtraPredicateProvider.class)
List<M8Province> list = easyEntityQuery.queryable(M8Province.class)
.configure(s->s.getBehavior().add(EasyBehaviorEnum.ALL_SUB_QUERY_GROUP_JOIN))
.where(m -> {
m.cities().any(c->{
c.id().eq("c1");
c.name().eq("杭州");
c.areas().flatElement().name().eq("上城区");
});
m.id().eq("p1");
}).toList();
WhereConditionProvider
新增WhereConditionProvider接口支持用户自定义实现@EasyWhereCondition的查询的默认比较符
include+limit
3.0.78默认将include+limit由union all变为partition by的实现
includeBy
在多次include下嵌套结构很难编写所以eq提供了includeBy方便用户在多次调用下进行额外操作
List<SchoolClass> list = easyEntityQuery.queryable(SchoolClass.class)
.includeBy(s -> Include.of(
s.schoolTeachers().flatElement().schoolClasses().asIncludeQueryable().where(a -> a.name().like("123")),
s.schoolStudents().flatElement().schoolClass().asIncludeQueryable().where(x -> x.schoolStudents().flatElement().name().eq("123")),
s.schoolStudents().asIncludeQueryable().where(x -> x.name().eq("123"))
))
.toList();比如s.schoolTeachers().flatElement().schoolClasses().asIncludeQueryable()会查询schoolTeachers和schoolClasses只要是路径上的都会被自动查询,如果需要对路径某个节点进行额外操作就单独处理该路径即可
cteviewer
a表是一个自关联表,其中a表的pid在b表中,所以我们需要使用a join b来获取变成一张cteviewer然后进行自关联
whereObject
支持对象筛选隐式关系
@Data
public class SysUserQueryDTO {
@EasyWhereCondition(propName = "bankCards.code")
private String bankCardCode;
@EasyWhereCondition(propName = "bankCards.type")
private String bankCardType;
@EasyWhereCondition(propName = "bankCards.bank.name", type = EasyWhereCondition.Condition.IN)
private List<String> bankCardBankNames;
}
SysUserQueryDTO queryDTO = new SysUserQueryDTO();
queryDTO.setBankCardCode("123");
queryDTO.setBankCardType("储蓄卡");
queryDTO.setBankCardBankNames(Arrays.asList("工商银行","建设银行"));
List<SysUser> list = easyEntityQuery.queryable(SysUser.class)
.whereObject(queryDTO)
.toList();sharding union all
3.0.57支持分片使用union all这样可以保证大部分复杂sql都支持
List<Map<String, Object>> list = easyEntityQuery.queryable(TopicSharding.class)
.configure(s->s.getBehavior().addBehavior(EasyBehaviorEnum.SHARDING_UNION_ALL))
.where(t -> {
t.id().in(Arrays.asList("20000","20001"));
})
.groupBy(t -> GroupKeys.of(t.createTime()))
.select(group -> {
MapProxy mapProxy = new MapProxy();
mapProxy.put("createTime", group.groupTable().createTime());
mapProxy.put("idCount", group.count(t -> t.id()));
return mapProxy;
}).toList();filter
3.0.48 o.user().filter(u->{}) o.userList().filter(u->{}) 后续的隐式join增加on条件，后续的隐式子查询增加where，隐式group增加
List<Draft2<String, Long>> list = easyEntityQuery.queryable(DocUser.class)
.subQueryToGroupJoin(o -> o.bankCards())
.where(user -> {
//后续user下的bankCards自动携带对应的条件包括select和order里面
user.bankCards().filter(x -> {
//支持隐式join和普通属性筛选
x.bank().name().eq("银行");
x.type().like("45678");
});
user.bankCards().any();
}).select(user -> Select.DRAFT.of(
user.name(),
user.bankCards().count()
)).toList();
List<SysBankCard> list = easyEntityQuery.queryable(SysBankCard.class)
.where(bank_card -> {
//后续SysBankCard下的bank自动携带对应的条件包括select和order里面
bank_card.bank().filter(t -> {
t.or(() -> {
t.name().like("工商银行");
t.name().contains("建设银行");
});
});
bank_card.bank().name().contains("123");
}).toList();PropagationValueFilter
3.0.46支持filterConfigure,实现PropagationValueFilter的接口支持filterConfigure传递
List<SysBank> list = easyEntityQuery.queryable(SysBank.class)
.filterConfigure(NotNullOrEmptyValueFilter.DEFAULT_PROPAGATION_SUPPORTS)
.where(bank -> {
bank.name().eq("");
bank.bankCards().any(s -> s.type().eq(""));
}).toList();offsetChunk
3.0.37因为toChunk有时候会对返回结果进行处理,导致chunk不准确,所以用户可以自行进行偏移量处理
easyEntityQuery.queryable(BlogEntity.class)
.orderBy(b -> b.createTime().asc())
.orderBy(b -> b.id().asc())
.offsetChunk(3, chunk -> {
for (BlogEntity blog : chunk.getValues()) {
a.incrementAndGet();
}
//偏移量为本次查询到的结果
return chunk.offset(chunk.getValues().size());
});
easyEntityQuery.queryable(BlogEntity.class)
.orderBy(b -> b.createTime().asc())
.orderBy(b -> b.id().asc())
.offsetChunk(100, chunk -> {
for (BlogEntity blog : chunk.getValues()) {
a.incrementAndGet();
}
//不进行偏移
return chunk.offset(0);
});partition by order
3.0.36^支持navigate添加属性partitionOrder默认没有排序则报错
/**
* 用户拥有的银行卡数
*/
@Navigate(value = RelationTypeEnum.OneToMany, selfProperty = {"id"}, targetProperty = {"uid"},orderByProps = {
@OrderByProperty(property = "openTime",asc = true),
@OrderByProperty(property = "code",asc = false,mode = OrderByPropertyModeEnum.NULLS_FIRST),
},partitionOrder = PartitionOrderEnum.NAVIGATE)
private List<SysBankCard> bankCard4s;
-- 对应sql
PARTITION BY t1.`uid` ORDER BY t1.`open_time` ASC,CASE WHEN t1.`code` IS NULL THEN 0 ELSE 1 END ASC,t1.`code` DESCtrigger
3.0.35^增加表达式triiger
easyQueryClient.addTriggerListener(triggerEvent -> {
//business
});内联视图后续隐式查询
3.0.31^

.select(group -> new BankCardGroupBOProxy()
.uid().set(group.key1())
.count().set(group.count())
).selectAutoInclude(BankCardSelectAutoInclude.class).toList();appendOn
3.0.30^隐式join需要添加on额外条件
List<SysBankCard> list = easyEntityQuery.queryable(SysBankCard.class)
.where(bank_card -> {
bank_card.bank().appendOn(t -> {
t.or(() -> {
t.name().like("工商银行");
t.name().contains("建设银行");
});
});
bank_card.bank().name().contains("123");
}).toList();includeMany
3.0.29^多层级include实现优化
List<SchoolClass> list = easyEntityQuery.queryable(SchoolClass.class)
.includeMany(s -> {
return new Include<>(s.schoolTeachers().flatElement().schoolClasses())
.where(a -> a.name().like("123"))
.thenInclude(s.schoolStudents().flatElement().schoolClass())
.where(x -> x.schoolStudents().flatElement().name().eq("123"))
.thenInclude(s.schoolStudents())
.where(x -> x.name().eq("123"));
}).toList();search
3.0.27^由三方作者提供pr扩展相关
ClassProxy
3.0.26^支持非@EntityProxy也能继续链式
List<TopicTypeTest1> list = easyEntityQuery.queryable(TopicTypeTest1.class)
.select(t -> new ClassProxy<>(TopicTypeTest1.class)
.field(TopicTypeTest1.Fields.topicType).set(t.topicType())
).toList();whereObject
3.0.24^支持range单属性(集合或数组)whereObject注解
@EasyWhereCondition(type = EasyWhereCondition.Condition.RANGE_OPEN,propName = "publishTime")
private List<LocalDateTime> publishTimeOpen;valueConvert
3.0.22^支持临时堆返回结果进行自定义处理 (入参可能为null)
List<Topic> list = easyEntityQuery.queryable(Topic.class)
.select(t_topic -> {
return new TopicProxy()
.stars().set(t_topic.stars())
.title().set(t_topic.stars().valueConvert(s -> s + "-"))
.createTime().set(t_topic.createTime())
.id().set(t_topic.createTime().format("yyyy-MM-dd HH:mm:ss").valueConvert(s->s+".123"));
}).toList();
