SpringBoot -- 集成MongoDB

前置工作

• 熟悉本系列的工作环境
• MongoDB已经搭建完成
• MongoDB启用验证

引入&配置参数

引入 spring-boot-starter-data-MongoDB

build.gradle

compile ('org.springframework.boot:spring-boot-starter-data-mongodb:'+springBootVersion)

配置Mongodb参数

• uri: mongodb://dev_xxx:dev_xxx@127.0.0.1:27017/kakme
• dev_xxx:dev_xxx 为 username:password
• kakme 为database
• 如果用户名密码中带有URI特殊字符（”:”,”@”）,请使用host方式

URI 方式：application.yml

spring:  data:    mongodb:      uri: mongodb://dev_xxx:dev_xxx@127.0.0.1:27017/kakme

使用MongoRepository进行CRUI操作

创建Mongodb Bean，使用@Id标识 ObjectId

MessageInfo.Java

/** * @author cwenao * @version $Id MessageInfo.java, v 0.1 2017-01-30 12:29 cwenao Exp $$ */public class MessageInfo {    @Id    private String id;    private String title;    private String msgType;    private String msgInfo;    //getter setter    ... ...    @Override    public String toString() {        return "[ id ="+id+", title ="+title+", msgInfo="+msgInfo+" ]";    } }

自定义Repository进行额外的操作，集成 MongoRepository

MsgInfoRepository.java,此为 interface

/** * @author cwenao * @version $Id MsgInfoRepository.java, v 0.1 2017-01-30 12:33 cwenao Exp $$ */public interface MsgInfoRepository extends MongoRepository<MessageInfo,String> {    MessageInfo queryMsgInfoByTitle(String title);}

创建 controller，使用上几章的 UserInfoController

UserInfoController

/** * @author cwenao * @version $Id UserInfoController.java, v 0.1 2017-01-25 18:35 cwenao Exp $$ */@Controllerpublic class UserInfoController extends AbstractCacheSupport {    @Autowired    MsgInfoRepository msgInfoRepository;    @RequestMapping("/messageInfo")    public String messageInfo(String title, ModelMap modelMap) {        MessageInfo messageInfo = new MessageInfo();        messageInfo.setMsgInfo("hello world !");        messageInfo.setTitle(title);        messageInfo.setMsgType("1");        msgInfoRepository.save(messageInfo);          modelMap.addAttribute("test_mongodb",            msgInfoRepository.queryMsgInfoByTitle("cwenao").toString());        return "userinfo/accountInfo";    }}
