我有一个多模块项目结构,如:

- application (parent module)
--- boot (web-app)
----- src/main/resources/templates/layout.html

---- todo (jar file)
----- src/main/resources/templates/home.html

在我的控制器上:

@RequestMapping(value = "/home")
public String home() {
    return "todo/home";
}

我收到如下错误消息:

Error resolving template "todo/home", template might not exist or
might not be accessible by any of the configured Template 
Resolvers]

是否需要配置专门用于spring的东西来在类路径上搜索模板？

UPDATE

解决了.添加以下属性可以解决我的问题:

- application (parent module)
--- boot (web-app)
----- src/main/resources/templates/layout.html

---- todo (jar file)
----- src/main/resources/templates/home.html

我的模型包含geojson点.找到最接近弹簧数据的方法很简单,但如何找到最近的位置以获得给定路线？

我从谷歌获取路线信息:

http://maps.googleapis.com/maps/api/directions/xml?origin=48.208174,16.373819&destination=48.340670,16.717540&sensor=false&units=metric&mode=driving

我正在使用Alamofire的SessionManager向我的API服务发出请求.

有没有办法限制Alamofire的重试次数？

我正在使用新的RequestAdapter和RequestTrier Protocols在Alamofire v4中提供重试机制.

我想将重试次数限制为5.如果在5次重试之后,则不应该执行新请求.

class VMRetrier: RequestAdapter, RequestRetrier {

public func adapt(_ urlRequest: URLRequest) throws -> URLRequest {
    return urlRequest;
}

func should(_ manager: SessionManager, retry request: Request, with error: Error, completion: @escaping RequestRetryCompletion) {

    if let response = request.task?.response as? HTTPURLResponse, response.statusCode == 401 {
        VMLogger.shared.debug(message: "Trying to get a token")
        let _ = AuthService.shared.login(email: "a@a.com", password: "test34")
                           .then(execute: { (response) in
                                completion(true, 0.0)
                           })
    }
    else {
        completion(false, 0.0)
    }
} }

用法:

internal let sessionManager …

我有一个已知的问题,即将UIButton添加到UIBarButtonItem中.我已尝试添加自动布局约束,如stackoveflow中所示,但我收到如下所述的错误.

UIButton *sortButton = [UIButton buttonWithType:UIButtonTypeCustom];
[sortButton setFrame:CGRectMake(10, 0, 100, 30)];
[sortButton setTitle:@"Sort" forState:UIControlStateNormal];
[[sortButton titleLabel] setFont:[UIFont boldSystemFontOfSize:13]];
[sortButton setBackgroundImage:[UIImage imageNamed:@"backgroun-button.png"] forState:UIControlStateNormal];
[sortButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[sortButton addTarget:self action:@selector(sortCollection:) forControlEvents:UIControlEventTouchUpInside];
[sortButton applyNavBarConstraints:100 height:30];

[self setSortCollection:item];

[self setToolbarItems:[NSArray arrayWithObjects:self.sortCollection, nil]];

Autolayout约束:

- (void)applyNavBarConstraints:(CGFloat)width height:(CGFloat)height
{
    if (width == 0 || height == 0) {
        return;
    }

    NSLayoutConstraint* w = [self.widthAnchor constraintEqualToConstant:width];
    NSLayoutConstraint * h = [self.heightAnchor constraintEqualToConstant:height];

    [w setActive:YES];
    [h setActive:YES];
}

我的应用程序使用SockJS和Spring Framework.我的服务器上有一个反向代理,用于将https请求重定向到tomcat容器.配置:

<VirtualHost *:443>
    ProxyPreserveHost On

    ProxyPass /boot http://127.0.0.1:8080/boot/
    ProxyPassReverse /boot http://127.0.0.1:8080/boot/

        ServerName MY_DOMAIN.com

        SSLEngine on
        SSLProtocol all
        SSLCertificateFile /etc/apache2/ssl/muhamo.crt
        SSLCertificateKeyFile /etc/apache2/ssl/muhamo.key
        SSLCACertificateFile /etc/apache2/ssl/bundl.crt
</VirtualHost>

如何配置虚拟主机以将wss请求转发给我的应用程序？我收到如下错误消息:

我想用Swift用英文字母替换一些字符.替换代码:

let turkish = ["?", "?", "ü", "?", "ö", "ç"]
let english = ["i", "g", "u", "s", "o", "c"]

var city = "A?ri"
var result = ""

for i in 0..<turkish.count {
    var target = turkish[i]
    var destination = english[i]

    result = city.stringByReplacingOccurrencesOfString(target, withString: destination, options: NSStringCompareOptions.CaseInsensitiveSearch | NSStringCompareOptions.LiteralSearch, range: nil)
}

它不会用"g"代替"ğ".奇怪的是,如果我像这样直接输入:

result = city.stringByReplacingOccurrencesOfString("?", withString: "g", options: NSStringCompareOptions.CaseInsensitiveSearch | NSStringCompareOptions.LiteralSearch, range: nil)

它工作得很好.

当我第一次将值String赋给变量时,为什么不呢？
