Question

我正在尝试将此http://websystique.com/spring-security/spring-security-4-remember-me-example-with-hibernate/转换为Spring，Spring Security和Mybatis，这是我拥有的项目结构：

由于我使用Java配置，我想摆脱xml文件。但是当我运行该项目时，我遇到了以下问题：

（越来越多的日志记录）

我尝试解决问题，但我不知道如何修复......

更新：在我尝试llya提供的解决方案后，我得到了新的异常

Answer 1

您有NPE原因环境未自动装配。我不知道确切的原因，但您可以按照以下方式进行工作：got from here）：

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.vincent.configuration" })
@MapperScan(basePackages="com.vincent.mapper")
@PropertySource(value = { "classpath:application.properties" })
public class DatabaseConfig implements EnvironmentAware {

    private Environment environment;


    @Override
    public void setEnvironment(Environment arg0) {
        this.environment = arg0;
    }
    //skipped code here
}

<强> UPD
还有一个例外：ClassNotFoundException: org.apache.ibatis.cursor.Cursor因为org.mybatis:mybatis-spring:jar:1.3.0需要org.mybatis:mybatis:jar:3.4.0，所以将org.mybatis:mybatis从3.1.1升级为3.4.0。
还有一个例外Failed to parse expression 'isAuthenticated())'因为)上的'isAuthenticated())'中有不必要的右括号SecurityConfiguration:49

Answer 2

你添加了＆＃34; @ Service＆＃34;标记您的CurrentUserDetailsService类的开始？

@Service
public class CurrentUserDetailsService implements UserDetailsService

试图将spring + spring security + hibernate项目转换为spring + spring security + mybatis项目
