Postgresql 保存实体时出现Utf 8问题

我将SpringBoot2与jpa、hibernate和postgres一起使用

在我的身材里，格雷德尔，我有

tasks.withType（JavaCompile）{
options.compilerArgs=[“-Xlint:unchecked”、“-Xlint:deprecation”、“-parameters”]
options.encoding=“UTF-8”
}

我在这里贴了一些课程

我对utf8有问题

在调试中我看到了

    select
        nextval ('ignar.hibernate_sequence')
Hibernate: 
    select
        nextval ('ignar.samples_id_seq')
Hibernate: 
    insert 
    into
        ignar.samplings
        (available_for_test, build_date, color_id, dimension_id, machine_id, print, product_id, reception_date, remark, special_try, test_done, to_print, delay_before_doing_test, press, quantity_received, dtype, id, year) 
    values
        (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'TraditionalSamplings', ?, ?)

可能是您的字符导致了问题。。。尝试将其转换为java文件中的字符串

为什么您认为这是UTF-8问题？如t所写：错误：编码“UTF8”的字节序列无效：0x00这意味着您试图通过期望字节解码为UTF-8的内容从数据库中输入非UTF-8数据不知道我是否可以使用字符。。。但是用一根绳子。。那工作
