SqlEs快速入门

可以参考demo:https://github.com/czcuestc/sqles/tree/master/sqles-demo

1，使用SqlEs很简单，首先创建实体类，通过注解配置索引，示例如下：

@Document
@Setting(maxResultWindow = 1000)
public class TestEntity implements Serializable {
    private static final long serialVersionUID = -190806307024075427L;
    /**
     * id字段，作为实体对象的唯一标识，可以根据该字段快速查找记录。
     * id字段的值必须设置，若id不设置，则插入，更新，删除操作会失败。
     */
    @Id
    @LongField
    private Long id;

    /**
     * 添加了Highlight注解，默认会将搜索高亮结果内容放入highlight字段，highlight字段变量名默认为highlight+当前字段名，camel命名
     *
     */
    @Highlight
    @TextField(analyzer = Analyzer.IK_SMART)
    private String textField;

    /**
     * highlight字段
     */
    private String highlightTextField;

    @KeyWordField
    private String keywordField;

    @BoolField
    private Boolean boolField;

    @ByteField
    private Byte byteField;

    @ShortField
    private Short shortField;

    @ShortField
    private Short nullValue;

    @IntegerField
    private Integer integerField;

    /***
     * Routing注解可设置路由字段
     */
    @Routing
    @LongField
    private Long longField;

    @HalfFloatField
    private Float halfFloatField;

    @ScaledFloatField(scalingFactor = 100)
    private BigDecimal scaledFloatField;

    @FloatField
    private Float floatField;

    @DoubleField
    private Double doubleField;

    @DateField
    private String stringDateField;

    @DateField
    private Date dateField;

    @DateField
    private Long longDateField;

    @DateField
    private Time timeField;

    @DateField
    private Timestamp timestampField;

    @DateField
    private LocalTime localTimeField;

    @DateField
    private LocalDateTime localDateTimeField;

    @DateField
    private Instant instantField;

    /**
     * 记录score会默认放入该字段，也可以用@Score注解指定。
     */
    private float score;
}

2，配置连接字符串，和数据库配置一样，唯一区别es连接字符为jdbc:es//xxxx,多个es实例以逗号分隔。

spring:
  datasource:
    sqles:
      url: jdbc:es://localhost:9200/mall?useUnicode=true&characterEncoding=UTF-8&useSSL=false
      username: root
      password: 123
      driver-class-name: com.czcuestc.sqles.jdbc.Driver
      type: com.alibaba.druid.pool.DruidDataSource
      druid:
        initial-size: 15 #连接池初始化大小
        min-idle: 20 #最小空闲连接数
        max-active: 30 #最大连接数

3，配置mapper扫描注解

@SqlEsMapperScan(basePackages = "com.sqles.demo") 

SqlEsMapperScan扫描实体类配置和索引管理mapper。

MapperScan扫描es mapper配置和接口（es的mapper文件和数据库配置方式一样，你可以把es看成一个数据库，es提供了jdbc驱动，屏蔽了底层差异）,然后可以通过mybatis访问es了。

@Configuration
@MapperScan(basePackages = "com.sqles.demo.mapper")
@SqlEsMapperScan(basePackages = "com.sqles.demo")
public class DataSourceConfig {
    @ConfigurationProperties(prefix = "spring.datasource.sqles")
    @Bean(name = "sqles")
    public DataSource dataSource() {
        DataSource dataSource= DruidDataSourceBuilder.create().build();
        return dataSource;
    }
}
