[Solved] Uncaught (in promise) Error: Avoided redundant navigation to current location:

Add the following code to the routing file   router/index.js

//Solve the problem that vue-router in the navigation bar of ElementUI reports an error when repeatedly clicking the menu in version 3.0 or above
const originalPush = Router.prototype.push
Router.prototype.push = function push (location) {
  return originalPush.call(this, location).catch(err => err)
}

Good position!!!!!

Type

Defining a bean of type ‘org.springframework.data.redis.core.RedisTemplate‘ in your configuration.

The spring-boot integration redis startup project reports an error with the following message:
defining a bean of type 'org.springframework.data.redis.core.RedisTemplate' in your configuration.
orConsider defining a bean of type 'org.springframework.data.redis.core.StringRedisTemplate' in your configuration.
Modify the pom file
Change the

        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
        </dependency>

is changed to 

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

After modification, if you want to customize redistemplate, you can refer to the following configuration


    @Bean
    public RedisTemplate<String, Object> template(RedisConnectionFactory factory) {
        // Create RedisTemplate<String, Object>object
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        // Configuring the connection factory
        template.setConnectionFactory(factory);
        // Define the Jackson2JsonRedisSerializer serialization object
        Jackson2JsonRedisSerializer<Object> jacksonSeial = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        // Specify the field, field, get and set to be serialized, and the range of modifiers, ANY of which are included in private and public
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        // Specify the type of serialized input, the class must be non-final modified, final modified class, such as String, Integer, etc. will report an exception
        om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.WRAPPER_ARRAY);
        jacksonSeial.setObjectMapper(om);
        StringRedisSerializer stringSerial = new StringRedisSerializer();
        // redis key Serialization method used stringSerial
        template.setKeySerializer(stringSerial);
        // redis value Serialization method usedjackson
        template.setValueSerializer(jacksonSeial);
        // redis hash key Serialization method usedstringSerial
        template.setHashKeySerializer(stringSerial);
        // redis hash value Serialization method usedjackson
        template.setHashValueSerializer(jacksonSeial);
        template.afterPropertiesSet();
        return template;
    }
