关于mybatis-plus逻辑删除无效的问题

添加如下注解value代表默认值delval代表删除时的值

/**
     * 是否删除
     */
    @TableLogic(value = "0", delval = "1")
    @TableField(value = "del_flag")
    private Boolean delFlag;

下图是配置全部代码(如您知道上一步配置该添加到哪里,那就请忽略下面的代码配置)

import com.baomidou.mybatisplus.core.injector.DefaultSqlInjector;
import com.baomidou.mybatisplus.core.injector.ISqlInjector;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

/**
 * mybatis-plus配置
 **/
@Configuration
@MapperScan({"com.sjyf.gym.mapper.**", "com.sjyf.gym.mapper"})
public class MybatisPlusConfig {

    /**
     * 分页插件
     */
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }

    /**
     * 分页
     * @param builder
     * @return
     */
    @Bean
    public ObjectMapper objectMapper (Jackson2ObjectMapperBuilder builder) {
        ObjectMapper objectMapper = builder.createXmlMapper(false).build();
        SimpleModule simpleModule = new SimpleModule();
        // 直接将所有的Long类型转换为String
        simpleModule.addSerializer(Long.class, ToStringSerializer.instance);
        simpleModule.addSerializer(Long.TYPE, ToStringSerializer.instance);
        objectMapper.registerModule(simpleModule);
        return objectMapper;
    }

    /**
     * 逻辑删除
     * @return
     */
    @Bean
    public ISqlInjector sqlInjector(){
        return new DefaultSqlInjector();
    }

}
