Soap WebService NTLM Authentication with Apache CXF and Spring

Recently I had the "chance" to consume an old school WebService in good old SOAP on top of that it was a C# WebService using the dataset construct which is in itself a world of pain... but we will not talk about that here

A more easy thing to tackle is the NTLM authentication, below is how I implemented it using Spring and Spring boot :

1. Define a set of custom properties in the application.yaml file

application.yaml

1 2 3 4 5

ws:    base-url: "http://host/ws.asmx?wsdl"    username: "myusername"    password: "mypassword"    authentication: "NTLM"

2. Map the properties in application.yaml to a Java class

YamlConfig

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.context.properties.EnableConfigurationProperties; import org.springframework.stereotype.Component;     @Component @EnableConfigurationProperties @ConfigurationProperties(prefix = "app") @Data public class YAMLConfig {       private Ws ws;          @Data     public static class Ws {         private String baseUrl;         private String username;         private String password;         private String authentication;         }     }
