Spring3新特性
graalvm打包Springboot+Mybatis
项目源代码
https://github.com/cmdch2017/SpringNative_Graalvm_Mybatis
如何安装与运行
安装graalvm与配置环境
首先安装步骤参考这篇博客
https://blog.csdn.net/weixin_38943666/article/details/129505945
其次如何处理反射
https://blog.csdn.net/qq_32740973/article/details/131799510
第一步，直接拷贝我项目中的config文件夹到你的项目

第二步，pom.xml加入依赖
build>
plugins>
plugin>
groupId>org.graalvm.buildtools/groupId>
artifactId>native-maven-plugin/artifactId>
/plugin>
plugin>
groupId>org.springframework.boot/groupId>
artifactId>spring-boot-maven-plugin/artifactId>
/plugin>
/plugins>
/build>
第三步执行下面的语句
java -agentlib:native-image-agent=config-output-dir=D:eclipse_filenew_wsspringboot3-demo3srcmainresourcesMETA-INFnative-image -jar .springboot3-demo3-0.0.1-SNAPSHOT.jar
1、如上图所示，点击mvn clean
2、如上图所示，点击mvn install
3、执行反射编译语句
java -agentlib:native-image-agent=config-output-dir=C:DemosCommunicationInterface30003srcmainresourcesMETA-INFnative-image -jar .targetcomu300003-1.0.0-SNAPSHOT.jar
4、打开 x64 Native Toogls Command Prompt for VS 并 cd到项目文件夹
mvn -Pnative -DskipTests clean native:compile
5、PowerShell中进入项目target目录下
.graalvm.exe
遇到的零散问题
问题1
org.apache.catalina.LifecycleException: An invalid Lifecycle transition was attempted ([before_stop]) for component
用不了反射，所以需要这个文件去
package org.wxy.example.sqlite.config;

@Component
public class ClassReflectConfig {
static boolean begin = true;
// @Value("${scanclass}")
private Boolean scanclass=true;
@Autowired
private ThreadPoolTaskExecutor executorService;
@PostConstruct
public void init() {
if (scanclass) {
System.err.println("配置文件下 scanclass 开启了生成反射类");

}
synchronized (ClassReflectConfig.class) {
if (begin && scanclass) {

executorService.submit(() -> {

// 扫描系统第二级开始的包
String packageName = ClassReflectConfig.class.getPackageName();

// 可以在这个地方,添加除了服务以外其他的包,将会加入反射,以供graalvm生成配置

for (String spn : asList) {

}
}
}
private void handlerClass(Class clazz) {
if (clazz.equals(ClassReflectConfig.class)) {
// 跳过自己,避免形成循环
return;
}
executorService.submit(() -> {
try {
System.err.println("反射注入:" + clazz.getName());
// 生成所有的构造器

// 找到无参构造器然后实例化

field.get(newInstance);
} catch (Throwable e) {
}
}
System.err.println("反射注入完成:" + clazz.getName());
} catch (Throwable e) {
}
});
}
}
之后报错信息
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'sqliteController': Unsatisfied dependency expressed through field 'personService': Error creating bean with name 'personService': Unsatisfied dependency expressed through field 'dao': Error creating bean with name 'personMapper': Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

问题2 报错信息提示无法读取外部 DTD ‘mybatis-3-mapper.dtd’
无法读取外部 DTD ‘mybatis-3-mapper.dtd’, 因为 accessExternalDTD 属性设置的限制导致不允许 ‘http’ 访问。
允许对 ‘http’ 的访问：
如果你确定从 ‘http’ 地址下载 DTD 文件是安全的，可以配置解析器以允许对 ‘http’ 的访问。在SpringbootApplication 中，可以使用以下代码：
System.setProperty("javax.xml.accessExternalDTD", "all");
问题3 exe文件闪退日志
用powerShell打开
问题4 报错信息有提示http
加上支持http协议的参数

问题5 RestController层的问题
org.apache.catalina.LifecycleException: An invalid Lifecycle transition was attempted ([before_stop]) for component [StandardEngine[Tomcat]] in state [INITIALIZED]

或者是下面的Controller层报错
原因是你没按照网上的教程来，在加了问题1的ClassReflectConfig 内容后，mvn -Pnative -DskipTests clean native:compile之后，你得执行以下语句，注意这里C:Demosspringboot3-demo3-mastersrcmainresourcesMETA-INFnative-image还有.targetspringboot3-demo3-0.0.1-SNAPSHOT.jar的路径看你项目中的路径
java -agentlib:native-image-agent=config-output-dir=C:Demosspringboot3-demo3-mastersrcmainresourcesMETA-INFnative-image -jar .targetspringboot3-demo3-0.0.1-SNAPSHOT.jar
问题6 Mapper层问题
检查yml文件中是否配置好了
mybatis:
mapper-locations: classpath:mapper/*.xml
typeAliasesPackage: org.wxy.example.*.model
问题7 只支持mybaits，不支持mybatis-plus
mybatis-plus暂不支持，官方也回应暂时没有计划支持graalvm
问题8 报错信息中有sqlSessionFactory
@MapperScan(basePackages ="org.wxy.example.*.mapper",sqlSessionFactoryRef = "sqlSessionFactory")
打包成Docker核心总结
https://zhuanlan.zhihu.com/p/602486720?utm_id=0
下面将介绍把spring boot项目打包成docker镜像，大部分操作与上诉内容一致，但需要在自己本地电脑安装docker，这里需要修改一下pom文件中spring-boot-maven-plugin插件配置，如下所示
plugin>
groupId>org.springframework.boot/groupId>
artifactId>spring-boot-maven-plugin/artifactId>
configuration>
image>
builder>paketobuildpacks/builder:tiny/builder>
env>
BP_NATIVE_IMAGE>true/BP_NATIVE_IMAGE>
/env>
/image>
excludes>
exclude>
groupId>org.projectlombok/groupId>
artifactId>lombok/artifactId>
/exclude>
/excludes>
/configuration>
/plugin>
搭梯子运行下面的语句
1、在终端输入指令：mvn -Pnative spring-boot:build-image
2、打开docker desktop
3、在终端输入指令：端口号注意是你自己项目的端口号
docker run -itd -p 8001:8001 –name graalvm graalvm:0.0.1-SNAPSHOT
