spring boot集成mongodb最简单版

通过spring tools suite新建一个spring project。带maven的即可

pom.xml文件配置

新建实体类 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; } }

建立接口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); //自定义的方法 }

建立service类，写业务逻辑方法

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" ) //扫描指定目录下面的MongoRepositories接口 public class SysUserService{ @Autowired private SysUserRepository sysUserRepository; @RequestMapping("save") public String save(){ SysUser sysUser = new SysUser(); sysUser.setName("张三"); 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("张三"); } }

最后是控制器

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 //启注解事务管理 @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); } }

还有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
