spring4.3.7整合mongodb3.2.1

前几天写了个mongodb原生的工具类，参考“http://ylcodes01.blog.51cto.com/5607366/1933342”，

项目里需要做分布式，所以现在集成到spring中，今天结合spring-mongodb写了一些常用的工具。

#上述spring-mongodb.xml要注意的地方：由于现在用的是mongodb3.X版本，所以

就不要使用mongo:mongo标签了，要改成mongo:mongo-client，一些参数要改变了，

具体看下源码和文档即可。

可能报错如下：

mongo-options' is no longer supported for MongoDB

#上述pom.xml一定要注意一个问题：

当上述org.hibernate.version配置为5.0.2.Final改成5.4.1Final时，那么要多一个配置，如下：

<javax.el-version>2.2.4</javax.el-version>
<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>javax.el</artifactId>
<version>${javax.el-version}</version>
</dependency>

不然，也许会报错如下：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.LocalValidatorFactoryBean#0': Invocation of init method failed; nested exception is javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

Caused by: javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

Caused by: javax.el.ELException: Provider com.sun.el.ExpressionFactoryImpl not found

向AI问一下细节

spring4.3.7整合mongodb3.2.1
