说来惭愧，这本是一个不应该出现的错误：
pojo类中的部分代码：让composeGoodName使用ik分词器。

@Document(indexName = "seasonal",type = "escomposegood", shards = 4, replicas = 0)
public class ESComposeGood {
    
    @Id
    private Long id;
    @Field(type = FieldType.Text,analyzer = "ik_max_word")
    private String composeGoodName;
    @Field(type = FieldType.Integer)
    private Integer composeGoodPrice;
    @Field(type = FieldType.Long)
    private Long composeGoodType;
    @Field(type = FieldType.Integer)
    private Integer composeGoodStatus;
    @Field(type = FieldType.Integer)
    private Integer composeGoodWeight;
    @Field(type = FieldType.Keyword)
    private String composeGoodIcon;
    @Field(type = FieldType.Integer)
    private Integer composeGoodSales;
    }
   

意外发生了，程序跑不起来了，他告诉我：

[mapper [composeGoodName] has different [analyzer]]
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is

java.lang.IllegalArgumentException:
 Mapper for [composeGoodName] conflicts with existing mapping in other types:（这句才是错误的核心）

一番查找后发现如果在使用分词器之前将数据插入了Elasticsearch那么就会发生Elasticsearch无法解析的问题，也就是上述错误所以说：
解决方案：
在向Elasticsearch中插入数据之前就要给需要的进行分词的属性标记好解析，然后再插入数据即可解决问题！
