通過spring tools suite新建一個spring project。帶maven的即可
pom.xml檔案配置

新建實體類 SysUser
package entity;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
@Document
public class SysUser {
//mongodb需要指定ID
@Id
private long seqid;
private String name;
private String password;
private long roleId;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public long getRoleId() {
return roleId;
}
public void setRoleId(long roleId) {
this.roleId = roleId;
}
public long getSeqid() {
return seqid;
}
public void setSeqid(long seqid) {
this.seqid = seqid;
}
}
建立介面SysUserRepository extends MongoRepository
package mapper;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import entity.SysUser;
@Component
public interface SysUserRepository extends MongoRepository {
SysUser findByName(String name); //自定義的方法
}
建立service類，寫業務邏輯方法
SysUserService
package service;
import java.util.List;
import mapper.SysUserRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import entity.SysUser;
@Service
@EnableMongoRepositories(basePackages="mapper" ) //掃描指定目錄下面的MongoRepositories介面
public class SysUserService{
@Autowired
private SysUserRepository sysUserRepository;
@RequestMapping("save")
public String save(){
SysUser sysUser = new SysUser();
sysUser.setName("張三");
sysUser.setPassword("123456");
sysUser.setSeqid(1L);
sysUserRepository.save(sysUser);
sysUser = new SysUser();
sysUser.setName("李四");
sysUser.setPassword("123456");
sysUser.setSeqid(2L);
sysUserRepository.save(sysUser);
return "ok";
}
@RequestMapping("find")
public List find(){
return sysUserRepository.findAll();
}
@RequestMapping("findByName")
public SysUser findByName(){
return sysUserRepository.findByName("張三");
}
}
最後是控制器
package controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Import;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import service.SysUserService;
import entity.SysUser;
/**
* Created by wenchao.ren on 2014/4/26.
*/
@SpringBootApplication
//啟註解事務管理
@Controller
@Import (SysUserService.class )
public class SimpleController {
@Autowired
private SysUserService sysUserService;
@RequestMapping(value ="/hello", method = RequestMethod.GET)
@ResponseBody
public String hello(){
SysUser sysUser = new SysUser();
sysUserService.save();
SysUser sysUser2= sysUserService.findByName();
return sysUser2.getName();
}
public static void main(String[] args) {
SpringApplication.run(SimpleController.class, args);
}
}
還有applicationContext.properties
# mongodb note:mongo3.x will not use host and port,only use uri spring.data.mongodb.host=localhost spring.data.mongodb.port=27017 spring.data.mongodb.uri=mongodb://localhost:27017/springbootdb server.port=8011
