本文将主要介绍一下JOOQ查询篇的基本使用姿势，如果看完本文，会发现jooq的用法，和写sql基本上没啥两样

I. 项目搭建

本项目借助SpringBoot 2.2.1.RELEASE + maven 3.5.3 + IDEA进行开发

1. 项目依赖

关于如何创建一个SpringBoot的项目工程，不再本文的描述范围内，如有兴趣可以到文末的个人站点获取

在这个示例工程中，我们的选用h2dabase作为数据库（方便有兴趣的小伙伴直接获取工程源码之后，直接测试体验），因此对应的pom核心依赖如下

        <artifactId>h2</artifactId>
    </dependency>
</dependencies>

2. 数据准备

本文对应的项目工程，和前面介绍增加删除的一致，所以这里直接使用之前新增的数据

II. 使用姿势

0. 基本准备

测试类，初始化一些必要的依赖，如 dsl

@Repository
public class PoetQueryRepository {
    private static final PoetTB poetTable = PoetTB.POET;
    private static final PoetryTB poetryTable = PoetryTB.POETRY;

    @Autowired
    private DSLContext dsl;

    private RecordMapper<PoetPO, PoetBO> poetMapper;
    private RecordMapper<PoetryPO, PoetryBO> poetryMapper;

    @PostConstruct
    public void init() {
        // 转换
        poetMapper = dsl.configuration().recordMapperProvider().provide(poetTable.recordType(), PoetBO.class);
        poetryMapper = dsl.configuration().recordMapperProvider().provide(poetryTable.recordType(), PoetryBO.class);
    }
}

1. 主键查询

请注意下面的poetMapper.map，将record实体(包含数据库基本信息)转换为业务实体(POJO业务对象)

    /**
     * 主键查询
     *
     * @param id
     * @return
     */
    public PoetBO queryById(int id) {
        // select * from poet where id = xxx
        return poetMapper.map(dsl.selectFrom(poetTable).where(poetTable.ID.eq(id)).fetchOne());
    }
}

2. 查询指定字段

/**
 * 指定字段查询
 *
 * @param id
 * @return
 */
public String queryFieldsById(int id) {
    // select `name` from poet where id = xxx
    Record1<String> record = dsl.select(poetTable.NAME).from(poetTable).where(poetTable.ID.eq(id)).fetchOne();
    return record.get(poetTable.NAME);
}

3. 列别名

/**
 * 列别名
 *
 * @param id
 * @return
 */
public String queryFieldsById2(int id) {
    // select `name` as author from poet where id = xxx
    Record1<String> record =
            dsl.select(poetTable.NAME.as("author")).from(poetTable).where(poetTable.ID.eq(id)).fetchOne();
    return (String) record.get("author");
}

4. 条件查询

条件比较查询

/**
 * 条件比较
 *
 * @param id
 * @return
 */
public List<PoetBO> queryByNotEq(int id) {
    // select * from poet where id != xxx
    return dsl.selectFrom(poetTable).where(poetTable.ID.notEqual(id)).fetch().map(poetMapper);
}

public List<PoetBO> queryByIdGT(int id) {
    // select * from poet where id > xxx
    return dsl.selectFrom(poetTable).where(poetTable.ID.gt(id)).fetch().map(poetMapper);
}

public List<PoetBO> queryByIdGE(int id) {
    // select * from poet where id >= xxx
    return dsl.selectFrom(poetTable).where(poetTable.ID.ge(id)).fetch().map(poetMapper);
}

public List<PoetBO> queryByIdLT(int id) {
    // select * from poet where id < xxx
    return dsl.selectFrom(poetTable).where(poetTable.ID.lt(id)).fetch().map(poetMapper);
}

5. in查询

in / not 查询，原则上如非必要，一般不推荐是用not in查询

public List<PoetBO> queryByIdIn(List<Integer> ids) {
    // select * from poet where id in (xxx)
    return dsl.selectFrom(poetTable).where(poetTable.ID.in(ids)).fetch().map(poetMapper);
}

public List<PoetBO> queryByIdNotIn(List<Integer> ids) {
    // select * from poet where id not in (xxx)
    return dsl.selectFrom(poetTable).where(poetTable.ID.notIn(ids)).fetch().map(poetMapper);
}

6. between

1
2
3
4
public List<PoetBO> queryByIdBetween(int left, int right) {
    // select * from poet where id between a and b
    return dsl.selectFrom(poetTable).where(poetTable.ID.between(left, right)).fetch(poetMapper);
}

7. like查询

1
2
3
4
public List<PoetBO> queryByNameLike(String name) {
    // select * from poet where name like '%xxx%'
    return dsl.selectFrom(poetTable).where(poetTable.NAME.like("%" + name + " %")).fetch(poetMapper);
}

8. null查询

原则上，字段不建议支持null

1
2
3
4
public List<PoetBO> queryByNameIsNull() {
    // select * from poet where name is null;
    return dsl.selectFrom(poetTable).where(poetTable.NAME.isNull()).fetch(poetMapper);
}

9. 多查询条件

最简单的and/or查询

public PoetBO queryByIdAndName(int id, String name) {
    // select * from poet where name = xxx and id = xxx
    return dsl.selectFrom(poetTable).where(poetTable.ID.eq(id)).and(poetTable.NAME.eq(name)).fetchOne(poetMapper);
}

public List<PoetBO> queryByIdOrName(int id, String name) {
    // select * from poet where name = xxx or id = xxx
    return dsl.selectFrom(poetTable).where(poetTable.ID.eq(id)).or(poetTable.NAME.eq(name)).fetch(poetMapper);
}

10. 排序

请注意下多字段的排序使用姿势

public List<PoetryBO> queryByIdGtOrderByIdDesc(int id) {
    return dsl.selectFrom(poetryTable).where(poetryTable.ID.gt(id)).orderBy(poetryTable.ID.desc())
            .fetch(poetryMapper);
}

public List<PoetryBO> queryByIdGtOrderByPoetIdAndId(int id) {
    // 双字段的排序
    // select * from poetry where id > xxx order by poet_id asc, id asc
    return dsl.selectFrom(poetryTable).where(poetryTable.ID.gt(id))
            .orderBy(poetryTable.POET_ID.asc(), poetryTable.ID.asc()).fetch(poetryMapper);
}

11. 分页

public List<PoetryBO> queryLimit(int limit) {
    // select * from poetry limit xxx
    return dsl.selectFrom(poetryTable).limit(limit).fetch(poetryMapper);
}

public List<PoetryBO> queryLimit(int offset, int limit) {
    // select * from poetry limit xxx, xxx
    return dsl.selectFrom(poetryTable).limit(offset, limit).fetch(poetryMapper);
}

public List<PoetryBO> queryOffset(int offset, int limit) {
    // select * from poetry limit xxx, xxx
    return dsl.selectFrom(poetryTable).offset(offset).limit(limit).fetch(poetryMapper);
}

12. 测试输出

完整的测试输出如下，我们也开启了jooq的debug日志，因此可以看到最终真实执行的ip地址
