[BUG]2.0.6反序列化中List里面有Long类型字段报错com.alibaba.fastjson2.reader.FieldReaderListInt64

[waitlife]

版本：

2.0.6

实体类：

public class TeacherJson {
    private static final long serialVersionUID = 1L;

    @JsonProperty("user_serial")
    private Long userSerial;

    @JsonProperty("user_name")
    private String userName;

    private List<String> codes;

    @JsonProperty("dept_list")
    private List<DeptList> deptList;

    @JsonProperty("manage_class_ids")
    private List<DeptList> manageClassIds;

    @JsonProperty("user_deps")
    private List<String> userDeps;

    public Long getUserSerial() {
        return userSerial;
    }

    public void setUserSerial(Long userSerial) {
        this.userSerial = userSerial;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public List<String> getCodes() {
        return codes;
    }

    public void setCodes(List<String> codes) {
        this.codes = codes;
    }

    public List<DeptList> getDeptList() {
        return deptList;
    }

    public void setDeptList(List<DeptList> deptList) {
        this.deptList = deptList;
    }

    public List<DeptList> getManageClassIds() {
        return manageClassIds;
    }

    public void setManageClassIds(List<DeptList> manageClassIds) {
        this.manageClassIds = manageClassIds;
    }

    public List<String> getUserDeps() {
        return userDeps;
    }

    public void setUserDeps(List<String> userDeps) {
        this.userDeps = userDeps;
    }

    public String toJson() {
        return JSON.toJSONString(this);
    }

    @Override
    public String toString() {
        return this.toJson();
    }
}

public class DeptList {
    private static final long serialVersionUID = 1L;

    @JsonProperty("dept_id")
    private Long deptId;

    @JsonProperty("pt_node_path_name")
    private String ptNodePathName;

    @JsonProperty("dept_name")
    private String deptName;

    @JsonProperty("is_grade")
    private String isGrade;

    public Long getDeptId() {
        return deptId;
    }

    public void setDeptId(Long deptId) {
        this.deptId = deptId;
    }

    public String getPtNodePathName() {
        return ptNodePathName;
    }

    public void setPtNodePathName(String ptNodePathName) {
        this.ptNodePathName = ptNodePathName;
    }

    public String getDeptName() {
        return deptName;
    }

    public void setDeptName(String deptName) {
        this.deptName = deptName;
    }

    public String getIsGrade() {
        return isGrade;
    }

    public void setIsGrade(String isGrade) {
        this.isGrade = isGrade;
    }
}

调用方法：

JSONObject teacherObject = 调用函数;//此处返回正确的JSONObject
List teacherList = teacherObject.getList("records", TeacherJson.class);

样例数据：

{
"total": 1,
"records": {
"user_serial": 2201266,
"user_name": "朱忠恕",
"codes": [
"Teacher"
],
"dept_list": [
{
"dept_id": 200882,
"pt_node_path_name": "/测试学校",
"dept_name": "办公室",
"is_grade": 0
}
],
"manage_class_ids": [],
"user_deps": [
200882
]
}
}

报错提示：

com.alibaba.fastjson2.reader.FieldReaderListInt64

尝试方法：

修改实体DeptList中的deptId类型为String，且将它的getDeptId和setDeptId方法都修改为String类型，不会报错。

类的信息不完整，无法构造testcase，需要补充 WedsTeacherDeptList这个类的信息

[waitlife]

上面打错了，已更正。这里要科学上网，好麻烦，既卡又慢，还时断时续的

如这里， 是因为records这个字段不存在

[waitlife]

抱歉，样例数据少打了二个字段，teacherObject中实际上是有records这个字段的。
{
"total": 1,
"records": {
"user_serial": 2201266,
"user_name": "朱忠恕",
"codes": [
"Teacher"
],
"dept_list": [
{
"dept_id": 200882,
"pt_node_path_name": "/测试学校",
"dept_name": "办公室",
"is_grade": 0
}
],
"manage_class_ids": [],
"user_deps": [
200882
]
}
}

输入的是一个JSONObject，你想要的是一个List，你看下哪里搞错了？

https://oss.sonatype.org/content/repositories/snapshots/com/alibaba/fastjson2/fastjson2/2.0.7-SNAPSHOT/
针对你这种情况，我也做了支持，你可以用2.0.7-SNAPSHOT验证

[waitlife]

dept_list和manage_class_ids其实都是JSONArray对象数组来的，之前用1.X一直都可正常反序列化的。

这个 fix了吗 我这也遇到了类似的。不过我用的兼容包
com.alibaba
fastjson
2.0.7-SNAPSHOT
提示不存在

[wenshao]

@oday-xiexin 需要配置这个maven snapshot仓库

问题已经修复，请用新版本

谢谢！已解决
