mongo-lambda-query

a lambda-based object-oriented mongo query plug-in
基于lambda表达式,且面向对象的mongo数据库查询插件。


使用步骤:

  1. 引入maven依赖文件
        <dependency>
            <groupId>io.github.darmi7</groupId>
            <artifactId>mongo-lambda-query</artifactId>
            <version>1.1.0</version>
        </dependency>
    
  2. 开启插件注解,加上需要扫描mongo实体的包路径
    @EnableMongoLambdaQuery
    @EnableMongoRepositories(basePackages = "com.darmi.demo.repository.mongo")
    public class Application
    
  3. 编写查询代码
    @Repository
    public interface TaskRepository extends MongoRepository<Task, String> {
    
    default Page<Task> search(TaskCriteria taskCriteria) {
        return MongoLambdaQuery.lambdaQuery(Task.class)
                .is(Task::getName, taskCriteria.getName())
                .is(Task::getType, taskCriteria.getFuzzyName())
                .reg(Task::getName, taskCriteria.getName())
                .gt(Task::getPoints, taskCriteria.getPoints())
                .gt(Task::getCreated, taskCriteria.getBegin())
                .lt(Task::getCreated, taskCriteria.getEnd())
                .page(taskCriteria.getPagination());
    }
    
    default Page<Task> aggregate(TaskCriteria taskCriteria) {
        return MongoLambdaQuery.lambdaQuery(Task.class)
            .is(Task::getName, taskCriteria.getName())
            .is(Task::getType, taskCriteria.getFuzzyName())
            .reg(Task::getName, taskCriteria.getName())
            .gt(Task::getPoints, taskCriteria.getPoints())
            .gt(Task::getCreated, taskCriteria.getBegin())
            .lt(Task::getCreated, taskCriteria.getEnd())
            .aggregate(taskCriteria.getPagination());
    }
    

}

}
