Question

嗨，我正在尝试使用spring-session-data-redis，但它抛出异常，我正在使用带有生菜的springboot 2.0.4和springRedis数据（均为最新的vesrion）。

Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'sessionRepositoryFilterRegistration' defined in class path resource [org/springframework/boot/autoconfigure/session/SessionRepositoryFilterConfiguration.class]: Unsatisfied dependency expressed through method 'sessionRepositoryFilterRegistration' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name'org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'connectionFactory' defined in class path resource [com/netelixir/config/RedisHttpSessionConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory]: Factory method 'connectionFactory' threw exception; nested exception is java.lang.NoClassDefFoundError: io/lettuce/core/AbstractRedisClient

这是我的RedisHttpSessionConfig.java类，我在其中编写了RedisData的代码

import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@EnableRedisHttpSession
public class RedisHttpSessionConfig  {  
    @Bean
    public LettuceConnectionFactory connectionFactory() {
        return new LettuceConnectionFactory();
    }

}

这是我的SecurityConfig.java类

package com.xyz.config;

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.env.Environment;
    import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
    import org.springframework.security.config.annotation.web.builders.HttpSecurity;
    import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
    import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
    import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

    import com.netelixir.service.UserSecurityService;
    import org.springframework.session.web.http.HeaderHttpSessionIdResolver;
    import org.springframework.session.web.http.HttpSessionIdResolver;

    @Configuration
    @EnableWebSecurity
    public class SecurityConfig extends WebSecurityConfigurerAdapter {

        @Autowired
        private Environment env;

        @Autowired
        private UserSecurityService userSecurityService;

        private BCryptPasswordEncoder passwordEncoder() {
            return SecurityUtility.passwordEncoder();
        }

        private static final String[] PUBLIC_MATCHERS = {
                "/css/**",
                "/js/**",
                "/user/**"
        };

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().disable().cors().disable().httpBasic().and().authorizeRequests()
            .antMatchers(PUBLIC_MATCHERS).permitAll().anyRequest().authenticated();
        }

        @Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userSecurityService).passwordEncoder(passwordEncoder());
        }

         @Bean
        public HttpSessionIdResolver httpSessionIdResolver() {
            return HeaderHttpSessionIdResolver.xAuthToken(); 
        }
    }

Answer 1

将io.lettuce:lettuce-core添加为依赖项可以解决该异常。
