找不到构造函数 'java.lang.String' 的参数 0

Question

我的项目是用Grails 4开发的，实际上我正在从Grails 2升级到Grails 4。你能给我一个解决方案吗？我该如何解决？谢谢

错误：

 Parameter 0 of constructor in com.bv.session.AjaxAwareAuthenticationEntryPoint required a bean of type
     'java.lang.String' that could not be found. 

recourse.groovy:

beans = {

    authenticationEntryPoint(com.bv.session.AjaxAwareAuthenticationEntryPoint) {
        loginFormUrl = '/login/auth' 
        grailsUrlMappingsHolder = ref('grailsUrlMappingsHolder')
        portMapper = ref('portMapper')
        portResolver = ref('portResolver')
    }

} 

Class:

public class AjaxAwareAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint {

    private UrlMappingsHolder proxyBean;
    public AjaxAwareAuthenticationEntryPoint(String loginFormUrl) {
        super(loginFormUrl);
    }

    @Override
    protected String determineUrlToUseForThisRequest(final HttpServletRequest request,
                                                     final HttpServletResponse response, final AuthenticationException e){

        String controllerName = (String)proxyBean.match(request.getServletPath()).getParameters().get("controller");

        String ajaxHeader = ((HttpServletRequest) request).getHeader("X-Requested-With");

        if ("XMLHttpRequest".equals(ajaxHeader)){
            return "/login/auth?session_expired_ajax=true";

        }

        if(request.getSession(false).isNew() || "index.gsp".equals(controllerName)) {
            return "/login/auth";
        }else{
            return "/login/auth?session_expired=true";
        }
    }

    public void setGrailsUrlMappingsHolder(UrlMappingsHolder proxyBean) {
        this.proxyBean = proxyBean;
    }
}

工具：

• Grails 4
• Spring-安全4

19.3 The BeanBuilder DSL Explained

Using Constructor Arguments

Constructor arguments can be defined using parameters to each bean-defining method. Put them after the first argument (the Class):

bb.beans {
    exampleBean(MyExampleBean, "firstArgument", 2) {
        someProperty = [1, 2, 3]
    }
}

This configuration corresponds to a MyExampleBean with a constructor that looks like this:

MyExampleBean(String foo, int bar) {
   ...
}
