Java 忘记密码实现spring安全性

我正在尝试使用spring security实现“忘记密码”字段。但有一个错误，我试图解决，但找不到解决办法。我了解到，JpaRepository执行一些批处理和CRUD操作。My

user.java

model类具有所有字段（..email，resetToken）

UserRepositoryDao:

@Repository("userRepository")
public interface UserRepositoryForgetPassword extends JpaRepository<User, Long>{

     Optional<User> findByEmail(String email);
     Optional<User> findByResetToken(String resetToken);

}

public interface UserServiceForgetPassword {

    public Optional<User> findUserByEmail(String email);

    public Optional<User> findUserByResetToken(String resetToken);

    public void save(User user);
}

@Service("userServiceForgetPassword")
public class UserServiceForgetPasswordImpl implements UserServiceForgetPassword {

    @Autowired
    UserRepositoryForgetPassword userRepositoryForgetPassword;

    @Override
    @Transactional
    public Optional<User> findUserByEmail(String email) {
        return userRepositoryForgetPassword.findByEmail(email);
    }

    @Override
    @Transactional
    public Optional<User> findUserByResetToken(String resetToken) {
        return userRepositoryForgetPassword.findByResetToken(resetToken);
    }

    @Override
    @Transactional
    public void save(User user) {
        userRepositoryForgetPassword.save(user);
    }
}

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

    @RestController
    public class FogetPasswordController {

        @Autowired
        UserServiceForgetPassword userServiceForgetPassword;

        @Autowired
        EmailServiceForgetPassword emailServiceForgetPassword;

        @Autowired
        private BCryptPasswordEncoder bCryptPasswordEncoder;


        //Do the stuffs

}

控制器：

@Repository("userRepository")
public interface UserRepositoryForgetPassword extends JpaRepository<User, Long>{

     Optional<User> findByEmail(String email);
     Optional<User> findByResetToken(String resetToken);

}

public interface UserServiceForgetPassword {

    public Optional<User> findUserByEmail(String email);

    public Optional<User> findUserByResetToken(String resetToken);

    public void save(User user);
}

@Service("userServiceForgetPassword")
public class UserServiceForgetPasswordImpl implements UserServiceForgetPassword {

    @Autowired
    UserRepositoryForgetPassword userRepositoryForgetPassword;

    @Override
    @Transactional
    public Optional<User> findUserByEmail(String email) {
        return userRepositoryForgetPassword.findByEmail(email);
    }

    @Override
    @Transactional
    public Optional<User> findUserByResetToken(String resetToken) {
        return userRepositoryForgetPassword.findByResetToken(resetToken);
    }

    @Override
    @Transactional
    public void save(User user) {
        userRepositoryForgetPassword.save(user);
    }
}

        UserServiceForgetPassword userServiceForgetPassword;

        @Autowired
        EmailServiceForgetPassword emailServiceForgetPassword;

        @Autowired
        private BCryptPasswordEncoder bCryptPasswordEncoder;


        //Do the stuffs

}

我希望扩展

JpaRepository

时出错

已编辑

您需要在

UserRepositoryForgetPassword

界面上使用

@Repository

。并在

ApplicationContext.xml

文件配置中添加

@EnableJpaRepositories（basePackages={“com.demo.test.repository”}）

以扫描存储库类，并在

ApplicationContext.xml

文件中使用

扫描基本包和类注释。

您需要

• 通过使用

  @EnableJpaRepositories

  注释

  ApplicationContextConfig

  类来启用Spring数据JPA
• 配置Spring Data JPA为我们的存储库接口创建实现时扫描的

  基本包

因此，请在您的配置文件（

ApplicationContextConfig

）中添加：

请检查下面的配置类。正如M.Denium所建议的，您不必直接与SessionFactory合作。JPA基于EntityManager的概念工作。我已经做了必要的更改，以使其通过java配置工作。如果您使用的是spring boot，则可以使用application.properties执行大部分配置

    @Configuration
    @PropertySource(value = { "classpath:application.properties" })
    @EnableJpaRepositories(basePackages = "com.pulseBeatMaster.dao", entityManagerFactoryRef = "myEntityManagerFactory", transactionManagerRef = "myTransactionManager")
    public class ApplicationContextConfig {

        // To get properties from application.properties
        // Import @PropertySource(value = { "classpath:application.properties" })
        // Have to use environment.getRequiredProperty();

        @Autowired
        private Environment environment;

        @Bean(name = "dataSource")
        public DataSource getDataSource() {
            BasicDataSource dataSource = new BasicDataSource();
            dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
            dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
            dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
            dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));

            // normally
            // dataSource.setDriverClassName("com.mysql.jdbc.Driver");

            return dataSource;

要通过spring引导属性进行最小配置，只需检查以下内容

教程。

看起来您通常不会扫描存储库界面。我们需要查看您的JPA/Spring数据配置。@chrylis我注入了Spring启动程序数据JPA依赖项，并继续上面的编码。显示您的配置class@SangamBelose我在“编辑”中发布了我的配置类para您不需要SessionFactory之类的东西，因为Spring boot已经为您配置了JPA

EntityManagerFactory

。删除所有本机hibernate资源。这基本上适用于

数据源

只要使用适当的

spring.DataSource.*

属性，您也可以删除它。现在，关于您的异常，请确保Spring Boot主类位于根包中。因此，它涵盖了扫描的所有子包，在您的情况下，

com.pulseBeatMaster

。他使用的是Spring Boot，当检测到时，它会自动启用Spring数据JPA。您不需要显式地启用它。也不需要向界面添加

@Repository

。还有XML文件中的注释吗？你如何看待这种情况？
