Question

这是我的主要课程：

static Logger logger;
static StringUtils stringUtils;

//java -cp ... <VM argument> main.class.Name <program arguments>
public static void main(String... args) throws ClassNotFoundException, IOException {
    logger = InjectorSingleton.getInstance().guiceInjector.getInstance(Logger.class);
    stringUtils = InjectorSingleton.getInstance().guiceInjector.getInstance(StringUtils.class);
}

这是我的模块类：

public class AppInjector extends AbstractModule {

    @Override
    protected void configure() {
        bind(Logger.class);
    }
}

我的记录器类是：

public class Logger {

    private StringUtils stringUtils;
    public boolean isDebug;

    @Singleton
    @Inject
    public Logger(StringUtils stringUtils) {
        this.stringUtils =  stringUtils;
        setIsVerbose();
    }


public class StringUtils {

    Logger logger;

    @Singleton
    @Inject
    public StringUtils(Logger logger) {
        this.logger = logger;
    }

我运行主类并获得此异常：

1) Tried proxying com.w.monitoring.headlessclient.utils.Logger to support a circular dependency, but it is not an interface.
  while locating com.w.monitoring.headlessclient.utils.Logger
    for parameter 0 at com.w.monitoring.headlessclient.utils.StringUtils.<init>(StringUtils.java:21)
  while locating com.w.monitoring.headlessclient.utils.StringUtils
    for parameter 0 at com.w.monitoring.headlessclient.utils.Logger.<init>(Logger.java:14)
  while locating com.w.monitoring.headlessclient.utils.Logger

1 error
    at com.google.inject.internal.InjectorImpl$3.get(InjectorImpl.java:1014)
    at com.google.inject.internal.InjectorImpl.getInstance(InjectorImpl.java:1040)

我将配置更改为：

@Override
protected void configure() {
    bind(Logger.class).toInstance(new Logger());
}

但是我应该如何初始化特定实例（缺少对ctor的args）

我应该在guice配置方法中修复什么？

尝试代理com.w.monitoring.headlessclient.utils.Logger以支持循环依赖，但它不是一个接口
