已经解决了，谢谢

@cssxsh 这个版本现在可以用么

如题

各位大佬，官方文档可以通过GlobalEventChannel过滤，但是我觉得比较麻烦，每个都需要去注册单独的事件。

现在我想像simbot那样，通过自定义注解加AOP去实现消息的过滤，有没有可实现的方法，或者说怎么加载AOP呢？

@cssxsh 我只是用kotlin写配置文件，其他都是java

build.gradle

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.9.0'
    id 'org.jetbrains.kotlin.plugin.serialization' version '1.9.0'
    id 'net.mamoe.mirai-console' version '2.15.0'
}

dependencies {
    implementation 'org.ini4j:ini4j:0.5.4'
    implementation 'com.alibaba.fastjson2:fastjson2:2.0.33'
    implementation 'com.squareup.okhttp3:okhttp:4.11.0'
    implementation 'net.mamoe.yamlkt:yamlkt-jvm:0.13.0'
    implementation 'mysql:mysql-connector-java:8.0.33'
    implementation 'cn.hutool:hutool-all:5.8.21'

}

group = 'com.ayang.plugin'
version = '1.1.5_bp'

repositories {
    maven { url 'https://maven.aliyun.com/repository/public' }
    mavenCentral()
}

@cssxsh 是的

package com.ayang.plugin

import kotlinx.serialization.Serializable
import net.mamoe.mirai.console.data.ReadOnlyPluginConfig
import net.mamoe.mirai.console.data.ValueDescription
import net.mamoe.mirai.console.data.value
import net.mamoe.yamlkt.Comment

/**

 * @description A3Bot配置文件
 * @date 2023-08-11 13:50:26
 */
object A3BotConfig : ReadOnlyPluginConfig("A3BotConfig") {

    @Serializable
    data class data(
        @Comment("驱动")
        val driver: String,
        @Comment("数据库地址")
        val url: String,
        @Comment("数据库用户名")
        val username: String,
        @Comment("数据库密码")
        val password: String,
    )

    @ValueDescription("数据库配置")
    val dataSource: MutableList<data> by value(mutableListOf(
        data(
            driver = "com.mysql.cj.jdbc.Driver",
            url = "jdbc:mysql://localhost:3306/a3bot?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai",
            username = "root",
            password = "admin"
        )
    ))
}

配置文件生成后：

# 数据库配置
dataSource: 
  - driver: com.mysql.cj.jdbc.Driver
    url: 'jdbc:mysql://localhost:3306/a3bot?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai'
    username: root
    password: admin

@cssxsh 不好意思

object A3BotConfig : ReadOnlyPluginConfig("A3BotConfig") {

    data class data(
        @Comment("驱动")
        val driver: String,
        @Comment("数据库地址")
        val url: String,
        @Comment("数据库用户名")
        val username: String,
        @Comment("数据库密码")
        val password: String,
    )

    @ValueDescription("数据库配置")
    val dataSource: MutableList<data> by value(mutableListOf(
        data(
            driver = "com.mysql.cj.jdbc.Driver",
            url = "jdbc:mysql://localhost:3306/a3bot?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai",
            username = "root",
            password = "admin"
        )
    ))
}

如图所示

两种注解都试了，而且还多一条横杠

@cssxsh 可以了，谢谢

@MrXiaoM 如果说，我让用户自己配置，然后我升级版本，增加了配置。怎么把新增的配置写入呢

@MrXiaoM 好的，我试试

启动后生成的文件：

直接修改这个文件的value

过一会儿自动就恢复成初始状态了

@Danile0 第5行多了个new FIle(); 忽略就行

@起舞弄清影
=。= ，这样就行了吧

try {
                        byte[] bytes = Base64.getDecoder().decode(stringR.getData());
                        String path = dataFile.getPath().substring(0, dataFile.getPath().length() - 9);
                        File file = new File(path + "serverInfo.png");
                        ImageIO.write(ImageIO.read(new ByteArrayInputStream(bytes)), "png", new File(file.getPath()));
                        ExternalResource resource = ExternalResource.create(file);
                        Image image = event.getGroup().uploadImage(resource);
                        MessageChain messageChain = new MessageChainBuilder()
                                .append(new At(event.getSender().getId()))
                                .append("\n")
                                .append(image)
                                .build();
                        event.getGroup().sendMessage(messageChain);
                    }catch (Exception e){
                        e.printStackTrace();
                        MessageUtil.sendGroupMessage(event, "获取图片失败!");
                    }

@起舞弄清影 在 求助！ 发送图片失败 中说：

你这明显是上传了不支持的格式
试试用ImageIO

我把文件命名为.png了呀
