springboot security oauth2问题汇总

1、Caused by: java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'loginController' method
loginController中存在重复的路由
2、mybatis启动报错：Consider defining a bean of type ‘com.newhope.interview.dao.UserMapper’ in your configuration.
提示dao层注入失败，检查了一下包结构，application在包的根目录下，正确，启动时自上而下扫描上下文。dao层已经添加了@Mapper注解。问题不知道出在哪里，更新jar包后才可以，修改pom文件：

       <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>1.3.2</version>
        </dependency>

修改为：

    <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.1</version>
        </dependency>

3、springboot整合thymeleaf报错：

Template might not exist or might not be accessible
