mongodb java spring_MongoDB和Java（4）：Spring Data整合MongoDB（XML配置）

最近花了一些时间学习了下MongoDB数据库，感觉还是比较全面系统的，涉及了软件安装、客户端操作、安全认证、副本集和分布式集群搭建，以及使用Spring Data连接MongoDB进行数据操作，收获很大。特此记录，以备查看。

2、mongodb配置文件

这个是spring的子配置文件，通过从.properties文件读取连接属性创建mongoClient对象，再创建DBFactory对象，通过DBFactory创建MongoTemplate，我们的数据层实现类就是使用MongoTemplate操作MongoDB的。

代码中把MongoTemplate注入到了实现类，然后使用它的API进行数据库操作。

5、Junit测试类

1 @RunWith(SpringJUnit4ClassRunner.class)2 @ContextConfiguration(locations = { “classpath:application.xml”})3 public classEmployeeDaoImplTest {4

5 @Autowired6 privateEmployeeDao employeeDao;7

8 @Autowired9 privateApplicationContext context;10

11 @Test12 public voidtestFindAll() {13 List list =employeeDao.findAll();14 for(Employee employee : list) {15 System.out.println(employee);16 }17 }18

19 @Test20 public voidtestInsertOneEmployee() {21 Employee e = new Employee(“admin”, 28);22 employeeDao.insertOneEmployee(e);23 }24

25 @Test26 public voidtestDeleteOneEmployeeByName() {27 employeeDao.deleteOneEmployeeByName(“admin”);28 }29

30 @Test31 public voidtestDeleteOneEmployee() {32 Employee e = employeeDao.findByName(“admin”);33 employeeDao.deleteOneEmployee(e.getId());34 }35

36 @Test37 public voidtestFindByName() {38 Employee e = employeeDao.findByName(“admin”);39 System.out.println(e);40 }41

42 @Test43 public voidtestFind() {44 Employee e = employeeDao.findByName(“admin”);45 Employee e2 =employeeDao.find(e.getId());46 System.out.println(e2);47 }48 }
