无法创建套接字工厂'com.google.cloud.sql.mysql.SocketFactory;' [英] Could not create socket factory 'com.google.cloud.sql.mysql.SocketFactory;'

问题描述

我似乎无法使它正常工作..

I can't seem to get this to work ..

我正在使用 Google灵活环境，并想连接到我的第二代云SQL 数据库.我目前遇到此异常:

I am using Google Flexible Environment and want to connect to my Second Generation Cloud SQL database. I am currently getting this exception:

[main] ERROR com.mahlzeit.server.BootstrappingServerConfig - Error trying to migrate SQL scripts ..
org.flywaydb.core.api.FlywayException: Unable to obtain Jdbc connection from DataSource
    at org.flywaydb.core.internal.util.jdbc.JdbcUtils.openConnection(JdbcUtils.java:56)
    at org.flywaydb.core.Flyway.execute(Flyway.java:1385)
    at org.flywaydb.core.Flyway.migrate(Flyway.java:1006)
    ...
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create socket factory 'com.google.cloud.sql.mysql.SocketFactory;' due to underlying exception:

    at java.lang.Class.forName(Class.java:264)
    at com.mysql.jdbc.MysqlIO.createSocketFactory(MysqlIO.java:3321)
    ...

这就是我配置DataSource的方式:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://google/mz_db?cloudSqlInstance=mz-test:us-central1:mz-life-cloudsql-prod&amp;socketFactory=com.google.cloud.sql.mysql.SocketFactory;" />
    <property name="username" value="root" />
    <property name="password" value="" />
</bean>

我添加了 mysql-socket-factory 作为依赖项:

<dependency>
    <groupId>com.google.cloud.sql</groupId>
    <artifactId>mysql-socket-factory</artifactId>
    <version>1.0.0</version>
</dependency>

那我为什么要得到这个例外?

so why am I getting this exception?

推荐答案

结尾处有分号，因此它试图加载名为com.google.cloud.sql.mysql.SocketFactory;的类.尝试在末尾删除分号.

You have a semicolon at the end so it's trying to load a class called com.google.cloud.sql.mysql.SocketFactory; Try removing the semicolon at the end.
