SpringBoot 错误总结

注意：所有文章除特别说明外，转载请注明出处.

1.错误：java.lang.UnsatisfiedLinkError: F:\Software\Apache-Tomcat\apache-tomcat-7.0.90\bin\tcnative-1.dll: Can’t load AMD 64-bit .dll on a IA 32-bit platform

解决：直接在网上下载一个 tcnative-1.dll 64位的复制到tomcat/bin目录下即可，这里是因为两者冲突造成。

2.错误：Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.

解决：排除此类的autoconfig。启动以后就可以正常运行。@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})

…

3.错误：Field userMapper in com.shop.service.impl.UserServiceImpl required a bean of type ‘com.shop.mapper.UserMapper’ that could not be found.

解决：这里是因为注解未找到对一个的mapper，所以报错，去inspections取消对应的提示。

4.新创建SQLSessionFactory

@Resource
private DataSource dataSource;

@Bean
public SqlSessionFactory sqlSessionFactory() throws Exception {
    SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
    sessionFactoryBean.setDataSource(dataSource);
    return sessionFactoryBean.getObject();
}

SLF4J: Class path contains multiple SLF4J bindings.

解决：表示maven棒我们引入了两个日志jar包，删掉其中一个便可。
