    实体

    1. @Document(indexName = "blog4", type = "article")
    2. public class UserEntity {
    3.     @Id
    4.     @Field(type = FieldType.Long, store = true)
    5.     private long id;
    6.     @Field(type = FieldType.Text, store = true, analyzer = "ik_max_word")
    7.     private String title;
    8.     @Field(type = FieldType.Text, store = true, analyzer = "ik_max_word")
    9.     private String content;
    10.     ……

    使用

    1. @Autowired
    2. private UserRepository userRepository;
    3. @Autowired
    4. private ElasticsearchTemplate elasticsearchTemplate;
    6. @Test
    7. public void createIndex() {
    8.     elasticsearchTemplate.createIndex(UserEntity.class);
    9.     elasticsearchTemplate.putMapping(UserEntity.class);
    10. }
    11. @Test
    12. public void testUserRepository() {
    13.     UserEntity user = new UserEntity();
    14.     user.setId(1);
    15.     user.setTitle("zhangsan");
    16.     user.setContent("123");
    17.     userRepository.save(user);
    18. }

    如果报错（实例化失败），添加运行时参数

    1. -Des.set.netty.runtime.available.processors=false
