使用spring-data遇到了一些问题，记录一下。
spring-data-elasticsearch版本选择
这里有一份官方github上的spring-data-elasticsearch与elasticsearch的对应关系表，但是不太完整，但是还是比较有参考价值的
| spring data elasticsearch | elasticsearch |
|---|---|
| 3.0.0.RC2 | 5.5.0 |
| 3.0.0.M4 | 5.4.0 |
| 2.0.4.RELEASE | 2.4.0 |
| 2.0.0.RELEASE | 2.2.0 |
| 1.4.0.M1 | 1.7.3 |
| 1.3.0.RELEASE | 1.5.2 |
| 1.2.0.RELEASE | 1.4.4 |
| 1.1.0.RELEASE | 1.3.2 |
| 1.0.0.RELEASE | 1.1.1 |
elasticsearch的客户端版本必须与服务端版本主版本保持一致。
参考：
The client must have the same major version (e.g. 2.x, or 5.x) as the nodes in the cluster. Clients may connect to clusters which have a different minor version (e.g. 2.3.x) but it is possible that new functionality may not be supported. Ideally, the client should have the same version as the cluster.
由于公司使用的elasticsearch 2.1.1，所以选择了spring-data-elasticsearch 2.1.7.RELEASE（2.1.7对应的原生客户端版本是elasticsearch 2.4.0，上面表格可能不完整）。
遇到异常java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotatedElementUtils.findMergedAnnotation
原因是项目使用的springframework版本为4.1.6，而spring-data-elasticsearch 2.1.7默认依赖的spring-context是4.3.11，所以初步确定是我们的项目使用的spring版本太低导致。
参考，发现原来AnnotatedElementUtils.findMergedAnnotation是4.2版才有的（since 4.2）。
@Field日期类型
@Field(type = FieldType.Date, index = FieldIndex.not_analyzed, format = DateFormat.custom, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZZ") @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZZ") private Date createTime;
@Document中动态indexName
配置Bean
@Component("esConfig")public class ESConfig { @Value("${app.env}") private String env; public String getEnv() { return env; } public void setEnv(String env) { this.env = env; }} @Document注解
@Document(indexName = "index-#{esConfig.env}", type = "typename", shards = 4, replicas = 1) 安装ik插件
从官网下载es版本对应版本的ik插件，
我开发环境安装的es是2.4.1，一开始放在了D:\Program Files\下，结果加入ik插件后就启动不了了，原来是不支持带空格的路径，换了路径就好了。（）
