我们来试试查询所有：

@Test
public void testFind(){
    // 查询全部，并安装价格降序排序
    Iterable<Item> items = this.itemRepository.findAll(Sort.by(Sort.Direction.DESC, "price"));
    items.forEach(item-> System.out.println(item));
}

结果：

编辑

5.4.5.自定义方法

Spring Data 的另一个强大功能，是根据方法名称自动实现功能。

比如：你的方法名叫做：findByTitle，那么它就知道你是根据title查询，然后自动帮你完成，无需写实现类。

当然，方法名称要符合一定的约定：

Keyword	Sample	Elasticsearch Query String
`And`	`findByNameAndPrice`	`{"bool" : {"must" : [ {"field" : {"name" : "?"}}, {"field" : {"price" : "?"}} ]}}`
`Or`	`findByNameOrPrice`	`{"bool" : {"should" : [ {"field" : {"name" : "?"}}, {"field" : {"price" : "?"}} ]}}`
`Is`	`findByName`	`{"bool" : {"must" : {"field" : {"name" : "?"}}}}`
`Not`	`findByNameNot`	`{"bool" : {"must_not" : {"field" : {"name" : "?"}}}}`
`Between`	`findByPriceBetween`	`{"bool" : {"must" : {"range" : {"price" : {"from" : ?,"to" : ?,"include_lower" : true,"include_upper" : true}}}}}`
`LessThanEqual`	`findByPriceLessThan`	`{"bool" : {"must" : {"range" : {"price" : {"from" : null,"to" : ?,"include_lower" : true,"include_upper" : true}}}}}`
`GreaterThanEqual`	`findByPriceGreaterThan`	`{"bool" : {"must" : {"range" : {"price" : {"from" : ?,"to" : null,"include_lower" : true,"include_upper" : true}}}}}`
`Before`	`findByPriceBefore`	`{"bool" : {"must" : {"range" : {"price" : {"from" : null,"to" : ?,"include_lower" : true,"include_upper" : true}}}}}`
`After`	`findByPriceAfter`	`{"bool" : {"must" : {"range" : {"price" : {"from" : ?,"to" : null,"include_lower" : true,"include_upper" : true}}}}}`
`Like`	`findByNameLike`	`{"bool" : {"must" : {"field" : {"name" : {"query" : "?*","analyze_wildcard" : true}}}}}`
`StartingWith`	`findByNameStartingWith`	`{"bool" : {"must" : {"field" : {"name" : {"query" : "?*","analyze_wildcard" : true}}}}}`
`EndingWith`	`findByNameEndingWith`	`{"bool" : {"must" : {"field" : {"name" : {"query" : "*?","analyze_wildcard" : true}}}}}`
`Contains/Containing`	`findByNameContaining`	`{"bool" : {"must" : {"field" : {"name" : {"query" : "?","analyze_wildcard" : true}}}}}`
`In`	`findByNameIn(Collection<String>names)`	`{"bool" : {"must" : {"bool" : {"should" : [ {"field" : {"name" : "?"}}, {"field" : {"name" : "?"}} ]}}}}`
`NotIn`	`findByNameNotIn(Collection<String>names)`	`{"bool" : {"must_not" : {"bool" : {"should" : {"field" : {"name" : "?"}}}}}}`
`Near`	`findByStoreNear`	`Not Supported Yet !`
`True`	`findByAvailableTrue`	`{"bool" : {"must" : {"field" : {"available" : true}}}}`
`False`	`findByAvailableFalse`	`{"bool" : {"must" : {"field" : {"available" : false}}}}`
`OrderBy`	`findByAvailableTrueOrderByNameDesc`	`{"sort" : [{ "name" : {"order" : "desc"} }],"bool" : {"must" : {"field" : {"available" : true}}}}`

例如，我们来按照价格区间查询，定义这样的一个方法：

public interface ItemRepository extends ElasticsearchRepository<Item,Long> {

    /**
     * 根据价格区间查询
     * @param price1
     * @param price2
     * @return
     */
    List<Item> findByPriceBetween(double price1, double price2);
}

然后添加一些测试数据：

@Test
public void indexList() {
    List<Item> list = new ArrayList<>();
    list.add(new Item(1L, "小米手机7", "手机", "小米", 3299.00, "http://image.leyou.com/13123.jpg"));
    list.add(new Item(2L, "坚果手机R1", "手机", "锤子", 3699.00, "http://image.leyou.com/13123.jpg"));
    list.add(new Item(3L, "华为META10", "手机", "华为", 4499.00, "http://image.leyou.com/13123.jpg"));
    list.add(new Item(4L, "小米Mix2S", "手机", "小米", 4299.00, "http://image.leyou.com/13123.jpg"));
    list.add(new Item(5L, "荣耀V10", "手机", "华为", 2799.00, "http://image.leyou.com/13123.jpg"));
    // 接收对象集合，实现批量新增
    itemRepository.saveAll(list);
}
