1.先自定义 TokenServices方法

/**
     * <p>注意，自定义TokenServices的时候，需要设置@Primary，否则报错，</p>
     *
     * @return
     */
    @Primary
    @Bean
    public DefaultTokenServices defaultTokenServices() {
        DefaultTokenServices tokenServices = new DefaultTokenServices();
        tokenServices.setTokenStore(tokenStore());
        tokenServices.setSupportRefreshToken(true);
//        tokenServices.setClientDetailsService(customClientDetailsService);
        // token有效期自定义设置，90天
        tokenServices.setAccessTokenValiditySeconds(60 * 60 * 24 * 90);
        // refresh_token 90天
        tokenServices.setRefreshTokenValiditySeconds(60 * 60 * 24 * 90);
        return tokenServices;
    }

2. 然后在configure，添加endpoints.tokenServices(defaultTokenServices());

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints
            .allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST)
            .authenticationManager(authenticationManager)
            .approvalStore(approvalStore())
            .tokenStore(tokenStore())
            .tokenEnhancer(tokenEnhancer())
            .reuseRefreshTokens(false)
            .userDetailsService(userDetailsService)
            .accessTokenConverter(OpenHelper.buildAccessTokenConverter())
            .authorizationCodeServices(authorizationCodeServices());
    endpoints.setClientDetailsService(customClientDetailsService);
    endpoints.tokenServices(defaultTokenServices());

    // 自定义确认授权页面
    endpoints.pathMapping("/oauth/confirm_access", "/oauth/confirm_access");
    // 自定义错误页
    endpoints.pathMapping("/oauth/error", "/oauth/error");
    // 自定义异常转换类
    endpoints.exceptionTranslator(new OpenOAuth2WebResponseExceptionTranslator());
}
