Question

Step1：使用命令create app

grails create-app test

第2步：创建域

grails create-domain-class test

Step3：configue build.gradle

compile 'org.grails.plugins:mongodb'

Step4：configue application.yml

grails:
   mongodb:
       host: "localhost"
       port: 27017
       username: ""
       password: ""
       databaseName: "test"
environments:
development:
    dataSource:
        dbCreate: none
        url:jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
        logSql: true

Step5：在Test.groovy中使用mapWith

static mapWith="mongo"

Step6：在bootstrap中进行查询测试

println Test.findAll()

Stop7：运行grails app

grails run-app

错误是：

 org.springframework.jdbc.BadSqlGrammarException: Hibernate operation: could not prepare statement; bad SQL grammar [select this_.id as id1_0_0_, this_.version as version2_0_0_ from test this_]; nested exception is org.h2.jdbc.JdbcSQLException: Table "TEST" not found; SQL statement:

        at org.grails.datastore.gorm.GormEntity$Trait$Helper$findAll$0.call(Unknown Source)

使用其他版本：

3.2.3没关系
3.2.5没关系
3.2.9没问题

我的代码是： the demo in github

3.3.0.M1和3.3.0.M2有什么变化？

environments:

            logSql: true
    test:

                minIdle: 5
                maxIdle: 25
                maxWait: 10000

                jdbcInterceptors: ConnectionState

将这些行替换为此

environments:
    development:
        grails:
            mongodb:
                host: "localhost"
                port: 27017
                username: ""
                password: ""
                databaseName: "test"
    test:
        mongodb:
                host: "localhost"
                port: 27017

                password: ""
                databaseName: "test"
    production:

            properties:

Grails 3.3.0 M1和3.3.0 M2组合MongoDB和Hibernate失败
