根据报错信息，看起来在使用 `Collectors.collectingAndThen()` 方法时，出现了将数组对象 `[Ljava.lang.Object;` 转换为 `MRegistMain` 的错误。这通常是由于查询结果集返回的类型不正确导致的。

您可以尝试使用 `Stream.map()` 方法来显式地将数组对象转换为 `MRegistMain` 对象。以下是修改后的代码示例：

import java.util.ArrayList;
import java.util.Comparator;
import java.util.List;
import java.util.TreeSet;
import java.util.stream.Collectors;

// ...

List<MRegistMain> mRegistMains = mPolicyMainDao.getRegistMainList(aggreeNo, name, identifyNo);

if (mRegistMains != null && !mRegistMains.isEmpty()) {
    List<MRegistMain> sortedAndDistinctMRegistMains = mRegistMains.stream()
            .map(obj -> (MRegistMain) obj) // 将数组对象转换为 MRegistMain 对象
            .collect(Collectors.collectingAndThen(Collectors.toCollection(() ->
                    new TreeSet<>(Comparator.comparing(MRegistMain::getRegistno))), ArrayList::new));

    // sortedAndDistinctMRegistMains 即为去重且按照 getRegistno 属性排序后的列表
    log.info("官网历史理赔查询结果集:: {}", sortedAndDistinctMRegistMains);
} else {
    // 处理结果集为空的情况
}

通过在 `map()` 方法中进行类型转换，将数组对象转换为 `MRegistMain` 对象。然后再进行去重和排序操作。

请注意，这只是一个示例代码片段，具体实现可能需要根据您的业务逻辑进行调整。希望能帮到您！如果您还有任何问题，请随时提问。

由于涉及到数据处理和代码实现，建议使用编程语言环境进行实现。以下是Python语言实现朴素贝叶斯分类器的示例代码：

import pandas as pd
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.naive_bayes import MultinomialNB

# 读取数据
data = pd.read_csv('spam.csv', encoding='latin-1')
# 删除无用的列
data.drop(['Unnamed: 2', 'Unnamed: 3', 'Unnamed: 4'], axis=1, inplace=True)
# 对列名进行重命名
data.columns = ['label', 'text']

# 将标签用数字表示
data['label'] = data['label'].map({'ham': 0, 'spam': 1})

# 划分训练集和测试集
train_data = data.sample(frac=0.8, random_state=1)
test_data = data.drop(train_data.index)

# 特征提取
vectorizer = CountVectorizer()
train_features = vectorizer.fit_transform(train_data['text'])
test_features = vectorizer.transform(test_data['text'])

# 训练模型
clf = MultinomialNB()
clf.fit(train_features, train_data['label'])

# 预测结果
predicted = clf.predict(test_features)

# 输出准确率
print('Accuracy:', clf.score(test_features, test_data['label']))

需要注意的是，以上代码仅为示例，具体实现可能需要根据数据的格式进行修改。此外，还可以使用更复杂的特征提取方法和模型调参来提高模型的准确率。
