将elasticsearch移动到一个大的磁盘空间```java@GetMapping("saveUser")public ArrayList<User> saveUser() {//添加索引mapping索引会自动创建但mapping自只用默认的这会导致分词器不生效 所以这里我们手动导入mappingRandom random = new Random();List<User> users = new ArrayList<>();for (int i = 0; i < 20; i++) {User user = new User();user.setId(i);user.setName(names[random.nextInt(9)]);user.setAge(random.nextInt(40) + i);user.setInfo(infos[random.nextInt(2)]);users.add(user);}ArrayList<User> users1 = (ArrayList<User>) esUserService.saveAll(users);return users1;}

elasticreposity插入会成功，但是返回会失败,这个可以选择去掉返回数值

问题二:

threw exception [Request processing failed; nested exception is org.springframework.dao.DataAccessResourceFailureException: Unable to parse response body for Response{requestLine=POST /_bulk?timeout=1m HTTP/1.1, host=http://localhost:9200, response=HTTP/1.1 200 OK}; nested exception is java.lang.RuntimeException: Unable to parse response body for Response{requestLine=POST /_bulk?timeout=1m HTTP/1.1, host=http://localhost:9200, response=HTTP/1.1 200 OK}] with root cause

java.lang.NullPointerException: null

解决方法:该问题肯是springboot与elasticserach版本不一致问题,数据导入不会失败,可以选择异常处理忽视该异常
