0614~ holiday self study

The previous content reviewed today , Some details have been modified ;

matters needing attention :

1. Alibaba cloud uploads pictures , Front page does not show , The back-end path splicing is written one less / ;

2. Payment callback results are not displayed , The intranet penetration path has not been changed ;

3. To configure json Global time format , Import can be used ;

package cn.itsource.config.date;

import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.boot.jackson.JsonComponent;
import org.springframework.context.annotation.Bean;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.TimeZone;

/**

 */
@JsonComponent
public class LocalDateTimeSerializerConfig {

    @Value("${spring.jackson.date-format:yyyy-MM-dd HH:mm:ss}")
    private String pattern;

    /**
     * Date Type global time formatting
     */
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilder() {
        return builder -> {
            TimeZone tz = TimeZone.getTimeZone("Asia/Shanghai");// Get time zone
            DateFormat df = new SimpleDateFormat(pattern);// Set format template
            df.setTimeZone(tz);
            builder.failOnEmptyBeans(false)
                    .failOnUnknownProperties(false)
                    .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
                    .dateFormat(df);
        }; }

    /**
     * LocalDate Type global time formatting
     */
    @Bean
    public LocalDateTimeSerializer localDateTimeDeserializer() {
        return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(pattern));
    }

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> builder.serializerByType(LocalDateTime.class, localDateTimeDeserializer());
    }
}

4. The payment function is done again , Familiar with the process ;
