[出现java.lang.NoClassDefFoundError: com/baomidou/mybatisplus/core/conditions/AbstractWrapper$$Lambda$798/831344888]

javaHBZ commented 1 year ago

问题描述

在我将对象转化为字符串的时候出现了这个问题,我用其他的工具包转化是没有问题的

环境信息

请填写以下信息：

OS信息： [e.g.：CentOS 8.4.2105 4Core 3.10GHz 16 GB]
JDK信息： [e.g.：Openjdk 1.8.0_312]
版本信息：[e.g.：Fastjson2 2.0.28]

重现步骤

如何操作可以重现该问题：

使用 JSON.toJSONString(Object obj) 方法
输入数据

出现 java.lang.NoClassDefFoundError: com/baomidou/mybatisplus/core/conditions/AbstractWrapper$$Lambda$798/831344888 错误

public static Object intercept(Invocation invocation) throws Throwable {
    MappedStatement mappedStatement = (MappedStatement) invocation.getArgs()[0];
    //请求参数
    Object parameter = null;
    if (1 < invocation.getArgs().length) {
        parameter = invocation.getArgs()[1];
    }
    BoundSql boundSql = mappedStatement.getBoundSql(parameter);
    String sql = boundSql.getSql();
    //执行的sql所在的mapper文件
    String resource = mappedStatement.getResource();
    //执行sql的dao文件的包名+方法名
    String daoMethod = mappedStatement.getId();
    //去除sql文中的换行
    sql = sql.replace("\n", "").replaceAll("\\s+", " ");
    if (SHOWSQL) {
        LOGGER.warn("\n" +
                        "[SQLMonitorPlugin]SQL监控：{}|{}\n" +//方法

                        "参数：{}", resource, daoMethod,
                sql, JSON.toJSONString(parameter));
    }
    try {
        long start = System.currentTimeMillis();
        Object e = invocation.proceed();
        long timeTicket = System.currentTimeMillis() - start;
        if (SLOWER < timeTicket) {
            LOGGER.warn("[SQLMonitorInterceptor]SQL监控：{}|{}，慢SQL（{}/{}ms）{}，参数：{}",
                    resource, daoMethod, timeTicket, SLOWER, sql, JSON.toJSONString(parameter));
        }
        if (e instanceof Collection) {
            int ct = ((Collection<?>) e).size();
            if (MAXCOUNT < ct) {
                LOGGER.warn("[SQLMonitorInterceptor]SQL监控：{}|{}，大集合（{}/{}）{}，参数：{}",
                        resource, daoMethod, ct, MAXCOUNT, sql, JSON.toJSONString(parameter));
            }
        }
        return e;
    } catch (Exception e) {
        LOGGER.warn("[SQLMonitorPlugin]SQL监控：{}|{}，执行出错：{}，参数：{}", resource, daoMethod,
                sql, JSON.toJSONString(parameter), e);
        throw e;
    }
}

期待的正确结果

成功转化为json字符串

这个问题升级到2.0.29应该就好了，你试试看

javaHBZ commented 1 year ago

还是会出现这个问题

wenshao commented 1 year ago

AbstractWrapper这个类的代码能提供下么？

wenshao commented 1 year ago

https://oss.sonatype.org/content/repositories/snapshots/com/alibaba/fastjson2/fastjson2/2.0.30-SNAPSHOT/ 问题已经修复，请帮忙用2.0.30-SNAPSHOT版本验证，2.0.30版本预计在5月9日前发布

是不是没有把rootCause发出来，错误堆栈中没看到fastjson的。没有rootCause的堆栈，不好诊断问题

加上JSONWriter.Feature.IgnoreErrorGetter试试看，比如：

JSON.toJSONString(object, JSONWriter.Feature.IgnoreErrorGetter);

wenshao commented 1 year ago

全局配置：

JSON.config(JSONWriter.Feature.IgnoreErrorGetter);

或者更新下快照，看下新版本是否会不加也不报错

做了这个处理： https://github.com/alibaba/fastjson2/commit/8fd9d6de2ab7ca504932ab5231237bd0c47dd347

javaHBZ commented 1 year ago

好的

javaHBZ commented 1 year ago

问题已经解决了,不加也可以,使用的快照版本是 fastjson2-2.0.30-20230429.134008-9.jar
