【junit5 读取yaml文件】读取localdate日期报错

问题描述
junit5解析yaml文件到实体类,加上 objectMapper.findAndRegisterModules(); 后,localdate格式的数据还是处理失败。

测试代码

    @Test
    void test1() throws IOException {
        ObjectMapper objectMapper = new ObjectMapper(new YAMLFactory());

        //加上这行代码,可以正确处理日期信息,否则读取日期会报错
        objectMapper.findAndRegisterModules();

        TypeReference<List<OrderList>> typeReference =
                new TypeReference<List<OrderList>>() {
        };
        List<OrderList> orderLists = objectMapper.readValue(
                new File("src/test/resources/demo.yaml"), typeReference);
        System.out.println(orderLists);

    }

实体类

package com.lx.entity;

import com.fasterxml.jackson.annotation.JsonProperty;

import java.math.BigDecimal;
import java.time.LocalDate;

public class OrderList {
    //如果yaml文件里的key和变量名相同,则不需要写这个注释
    @JsonProperty("item")
    private String item;
    @JsonProperty("quantity")
    private int quantity;
    @JsonProperty("unitPrice")
    private BigDecimal price;
    @JsonProperty("orderDate")
    private LocalDate date;

    public OrderList() {
    }

    public OrderList(String item, int quantity, BigDecimal price, LocalDate date) {
        this.item = item;
        this.quantity = quantity;
        this.price = price;
        this.date = date;
    }

    public String getItem() {
        return item;
    }

    public int getQuantity() {
        return quantity;
    }

    public BigDecimal getPrice() {
        return price;
    }

    public LocalDate getDate() {
        return date;
    }

    @Override
    public String toString() {
        return "OrderList{" +
                "item='" + item + '\'' +
                ", quantity=" + quantity +
                ", price=" + price +
                ", date=" + date +
                '}';
    }
}

yaml文件

- item: No.9 Spro
  quantity: 2
  unitPrice: 1.23
  orderDate : 2022-06-16
- item: No.1 XX (YeaH)
  quantity: 3
  unitPrice: 2.09
  orderDate : 2022-06-17

在pom里加上这个依赖看看,你加了自动注册模块的操作,但你的本地仓里边就没有对应的jar包,所以你在pom引入对应的包先


        <dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-jsr310</artifactId>
            <version>2.8.5</version>
        </dependency>

好的谢谢,我之前用的是2.13.2版本的,换成这个2.8.5就没问题了
