springboot initialization error on startup with mongodb on gorm/groovy

Question

Getting startup issues for this springboot project using MongoDB/GORM/Groovy on `Java 1.7.0_55`, gradle `1.11`, and `spring-boot-gradle-plugin:1.2.1.RELEASE`. I'm running the project as-is with the exception of the following change to `application.yml` for my remote mongodb: ``` spring: mongodb: host: "10.160.8.1" databaseName: "citydb" ``` **On startup, I'm seeing this bean initialization error with `mappingMongoConverter` ``` Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mongoTemplate' defined in class path resource [org/springframework/boot/autoconfigure/mongo/MongoDataAutoConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 1 of type [org.springframework.data.mongodb.core.convert.MongoConverter]: : Error creating bean with name 'mappingMongoConverter' defined in class path resource [org/springframework/boot/autoconfigure/mongo/MongoDataAutoConfiguration.class]: Unsatisfied depen…

Accepted Answer

`gorm-mongodb-spring-boot` is incompatible with Spring Boot 1.2. It creates a bean named `mongoMappingContext` that prevents `MongoDataAutoConfiguration` from creating its own bean with the same name. You should see a message like this in the log:

```
2015-02-25 14:01:30.731  INFO 60231 --- [           main] a.ConfigurationClassBeanDefinitionReader : Skipping bean definition for [BeanMethod:name=mongoMappingContext,declaringClass=org.springframework.boot.autoconfigure.mongo.MongoDataAutoConfiguration]: a definition for bean 'mongoMappingContext' already exists. This top-level bean definition is considered as an override.
```

You can work around the problem by declaring your own `org.springframework.data.mongodb.core.mapping.MongoMappingContext` bean with a different name, for example:

```
@Bean
MongoMappingContext springDataMongoMappingContext() {
    return new MongoMappingContext()
}
```
