常见的springboot整合配置类

MyBatisConfig：

@Configuration
public class MyBatisConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}

JacksonConfig：

@Configuration
public class JacksonConfig implements WebMvcConfigurer{

    private static final String DATE_PATTERN = "yyyy-MM-dd";
    private static final String TIME_PATTERN = "HH:mm:ss";
    private static final String DATETIME_PATTERN = "yyyyMMddHHmmss";
    public static final DateTimeFormatter DATETIME = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
    @Bean
    @Primary
    public ObjectMapper objectMapper() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        mapper.configure(SerializationFeature.WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS, false);
        mapper.configure(DeserializationFeature.FAIL_ON_IGNORED_PROPERTIES, false);
        mapper.registerModule(assembleJavaTimeModule());
        mapper.findAndRegisterModules();
        return mapper;
    }
    private JavaTimeModule assembleJavaTimeModule() {
        JavaTimeModule javaTimeModule = new JavaTimeModule();
        javaTimeModule.addSerializer(LocalDateTime.class,
                new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DATETIME_PATTERN)));
        javaTimeModule.addSerializer(LocalDate.class,
                new LocalDateSerializer(DateTimeFormatter.ofPattern(DATE_PATTERN)));
        javaTimeModule.addSerializer(LocalTime.class,
                new LocalTimeSerializer(DateTimeFormatter.ofPattern(TIME_PATTERN)));
        javaTimeModule.addDeserializer(LocalDateTime.class,
                new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DATETIME_PATTERN)));
        javaTimeModule.addDeserializer(LocalDate.class,
                new LocalDateDeserializer(DateTimeFormatter.ofPattern(DATE_PATTERN)));
        javaTimeModule.addDeserializer(LocalTime.class,
                new LocalTimeDeserializer(DateTimeFormatter.ofPattern(TIME_PATTERN)));
        return javaTimeModule;
    }
}

RedisConfig

@Configuration

        FastJson2JsonRedisSerializer serializer = new FastJson2JsonRedisSerializer(Object.class);

        ObjectMapper mapper = new ObjectMapper();

                ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
        serializer.setObjectMapper(mapper);

        redisTemplate.setValueSerializer(serializer);
        // 使用StringRedisSerializer来序列化和反序列化redis的key值
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    @Bean
    public HashOperations hashOperations(RedisTemplate redisTemplate) {
        return redisTemplate.opsForHash();
    }

    @Bean
    public ValueOperations valueOperations(RedisTemplate redisTemplate) {
        return redisTemplate.opsForValue();
    }

    @Bean
    public ListOperations listOperations(RedisTemplate redisTemplate) {
        return redisTemplate.opsForList();
    }

    @Bean
    public SetOperations setOperations(RedisTemplate redisTemplate) {
        return redisTemplate.opsForSet();
    }

    @Bean
    public ZSetOperations zSetOperations(RedisTemplate redisTemplate) {
        return redisTemplate.opsForZSet();
    }

    @Bean
    RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory) {

        RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        return container;
    }
}

        Contact contact = new Contact("tnar","http://www.baidu.com","");


        return new ApiInfoBuilder().title("xxxx接口文档")

                .version("1.0.0")
                .contact(contact)
                .build();


    }
    @Bean
    public Docket createRestApi(Environment environment) {

        //只有在dev环境或者sit环境才会显示swagger
        Profiles profiles = Profiles.of("dev","test");
        boolean enable = environment.acceptsProfiles(profiles);
        return new Docket(documentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .enable(enable)
                .select()
                .apis(RequestHandlerSelectors.basePackage("xxxx")) //这里写的是API接口所在的包位置
                .paths(PathSelectors.any())
                .build();
    }
