Can you help me?

Answer 1

You are using Spring Boot and are trying very hard not to use it, at least in your pom.xml . First you don't need the javaee-web-api dependency. The idea of the starters is that those manage all needed dependencies. So simply remove it. The same applies to the spring-boot-starter as that already is implied by the spring-boot-starter-web dependency.

You have defined a lot of additional plugins for which Spring Boot already has the needed configuration, which you are now overriding or even worse using a very old version. Remove all the plugins and leave only the Spring Boot one.

So what you basically need to do is simply strip your pom.xml which should leave you with something like the following.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0    http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

    <endorsed.dir>${project.build.directory}/endorsed</endorsed.dir>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.7</java.version>
</properties>
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.0.RELEASE</version>
</parent>   

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>   
    </plugins>
</build>
</project>

Pro Tip: I would suggest using a jar instead of a war that way you can simply deliver a jar file and do java -jar WebService.jar and have everything up and running in no time. You don't really need a war for that anymore.
