    看看下面的粗体字,description有没有setter方法?

    package com.imooc.luckymoney;

    import java.math.BigDecimal;

    import org.springframework.beans.factory.annotation.Value;

    import org.springframework.boot.context.properties.ConfigurationProperties;

    import org.springframework.stereotype.Component;

    @Component

    @ConfigurationProperties(prefix = "limit")

    public class LimitConfig {

    private BigDecimal minMoney;

    private BigDecimal maxMoney;

    private String description;

    public BigDecimal getMinMoney() {

    return minMoney;

    }

    public void setMinMoney(BigDecimal minMoney) {

    this.minMoney = minMoney;

    }

    public BigDecimal getMaxMoney() {

    return maxMoney;

    }

    public void setMaxMoney(BigDecimal maxMoney) {

    this.maxMoney = maxMoney;

    }

    public String getDescription() {

    return description;

    }

    public void setDescription(String description) {

    this.description = description;

    }


    }
