jooq

I have my Entities with Spring Data JPA, but to generate stats about them, I use jOOQ in a Spring @Repository . Since my methods return either a List of entities, or a Double , how can I expose them as links? Let's say I have a User entity, I want to get the following JSON: { "_embedded" : { "users" : [ ] }, "_links" : { "self" : { "href" : "http://localhost:8080/api/users" }, "stats" : { "href" : "http://localhost:8080/api/users/stats" } "profile" : { "href" : "http://localhost:8080/api/profile/users" } }, "page" : { "size" : 20, "totalElements" : 0, "totalPages" : 0, "number" : 0 } } And in

I'm experimenting with jOOQ and Kotlin and seen some tutorials and docs and it looks really nice. But if there is something very annoying with jOOQ is the code generation. It seems too complex, and eventually impossible to maintain. I decided to create my own table models (similar to how hibernate works). I created two table models: User data class User( val id: String = UUID.randomUUID().toString(), val name: String, val email: String, val password: String? = null ) { companion object { val TABLE: Table<Record> = DSL.table("user") val ID: Field<String> = DSL.field("id", String::class.java)

I am considering moving from Hibernate to jOOQ but I am not sure if I can do without caching. Hibernate has a first- and second-level cache . I know that jOOQ does have support for reusing prepared statements . Will I have to take care of caching on my own if I use jOOQ? Query caching / result caching: I'm mentioning this, because this kind of cache is also possible with Hibernate , and it might make sense under certain circumstances. In Hibernate, the query cache works closely with the second-level cache. In jOOQ, you can implement a query cache that intercepts all queries using the jOOQ

I have a table Table1 with 6 columns. Here is the sql statement that i need to map. Select *,count(ID) as IdCount from Table1; Now, the sql query result will be 7 columns ( 6 Table1 columns and 1 IdCount column). But when i implement the same in Jooq with this query, it only gets a single column "IDCount". SelectQuery q = factory.selectQuery(); q.addSelect(Table1.ID.count().as("IdCount")); q.addFrom(Table1.TABLE1); Now, the resultant recordset have only a single column "IdCount" while what i need is all the columns and one additional column "IdCount". I want 7 columns in Jooq too. Option 1

In following case StudentDao is JOOQ generated. public class ExtendedStudentDAO extends StudentDao { public ExtendedStudentDAO () { super(); } public ExtendedStudentDAO (Connection connection) { Configuration configuration = DSL.using(connection, JDBCUtils.dialect(connection)).configuration(); this.setConfiguration(configuration); } //adding extra methods to DAO using DSL public String getStudentName

[b]ORM已经过时了[/b] 最近几十年来，关于ORM究竟还有没有用的争论一直不断。很多人承认Hibernate和JPA确实很好的解决了不少实际的问题（通常是复杂对象的持久化），但有些人认为，对于面向数据的应用而言，复杂的映射关系则有点大材小用了。 JPA通过在目标类型上使用硬编码的注解，来建立标准的声明式的映射规则，进而完成映射关系。但我们认为，很多以数据为中心的应用不应该受限于注解的局限性，而应该通过一种函数式的方式来解决。Java 8的Steam API终于让我们可以用一种简洁的方式来解决这个问题了！ 我们先从一个简单的例子开始，这里我们使用H2的INFORMATION\_SCHEMA来查询所有的表及字段。我们专门用一个Map<String, List<String>>类型的数据结构来存储这个信息。我们用[url=http://blog.jooq.org]jOOQ[/url]来简化SQL的交互。下面来做一下准备工作： public static void main(String[] args) throws Exception { Class.forName("org.h2.Driver"); try (Connection c = getConnection( "jdbc:h2:~/sql-goodies-with-mapping", "sa", "")) { //
