+# spring 整合 mongodb（xml配置方式）
+
+## 一、说明
+
+### 1.1 项目结构说明
+
+配置文件位于resources下,项目以单元测试的方式进行测试。
+
+![spring+redis项目目录结构](D:\spring-samples-for-all\pictures\spring-mongodb.png)
+
+
+
+### 1.2 依赖说明
+
+除了spring的基本依赖外，需要导入mongodb整合依赖包
+
+```xml
+ <!--spring mongodb 整合依赖-->
+<dependency>
+    <groupId>org.springframework.data</groupId>
+    <artifactId>spring-data-mongodb</artifactId>
+    <version>2.1.3.RELEASE</version>
+</dependency>
+```
+
+
+
+## 二、spring mongodb
+
+#### 2.1 新建配置文件
+
+```properties
+mongo.host=192.168.200.228
+mongo.port=27017
+# 数据库名称. 默认是'db'.
+mongo.dbname=database
+# 每个主机允许的连接数
+mongo.connectionsPerHost=10
+# 线程队列数，它和上面connectionsPerHost值相乘的结果就是线程队列最大值。如果连接线程排满了队列就会抛出异常
+mongo.threadsAllowedToBlockForConnectionMultiplier=5
+# 连接超时的毫秒 0是默认值且无限大。
+mongo.connectTimeout=1000
+# 最大等待连接的线程阻塞时间 默认是120000 ms (2 minutes).
+mongo.maxWaitTime=1500
+# 保持活动标志，控制是否有套接字保持活动超时 官方默认为true 且不建议禁用
+mongo.socketKeepAlive=true
+# 用于群集心跳的连接的套接字超时。
+mongo.socketTimeout=1500
+```
+
+#### 2.2 整合配置
+
+```xml

+
+#### 2.3 测试整合
+
+```java
+/**

+ * @description : MongoDB 查询
+ */
+@RunWith(SpringRunner.class)
+@ContextConfiguration(locations = "classpath:mongodb.xml")
+public class MongoDBTest {

+    @Autowired
+    private MongoTemplate mongoTemplate;
+
+    @Test
+    public void insert() {
+        // 单条插入
+        mongoTemplate.insert(new Programmer("xiaoming", 12, 5000.21f, new Date()));
+        List<Programmer> programmers = new ArrayList<Programmer>();
+        // 批量插入
+        programmers.add(new Programmer("xiaohong", 21, 52200.21f, new Date()));
+        programmers.add(new Programmer("xiaolan", 34, 500.21f, new Date()));
+        mongoTemplate.insert(programmers, Programmer.class);
+    }
+
+    // 条件查询
+    @Test
+    public void select() {
+        Criteria criteria = new Criteria();
+        criteria.andOperator(where("name").is("xiaohong"), where("age").is(21));
+        Query query = new Query(criteria);
+        Programmer one = mongoTemplate.findOne(query, Programmer.class);
+        System.out.println(one);
+    }
+
+
+    // 更新数据
+    @Test
+    public void MUpdate() {
+        UpdateResult updateResult = mongoTemplate.updateMulti(query(where("name").is("xiaoming")), update("age", 35), Programmer.class);
+        System.out.println("更新记录数：" + updateResult.getModifiedCount());
+    }
+
+    // 删除指定数据
+    @Test
+    public void delete() {
+        DeleteResult result = mongoTemplate.remove(query(where("name").is("xiaolan")), Programmer.class);
+        System.out.println("影响记录数：" + result.getDeletedCount());
+        System.out.println("是否成功：" + result.wasAcknowledged());
+    }
