Answer 1

You have an error in RestController annotation definition. According to the docs it is:

public @interface RestController {

/** * The value may indicate a suggestion for a logical component name, * to be turned into a Spring bean in case of an autodetected component. * @return the suggested component name, if any * @since 4.0.1 */ String value() default "";

}

Which means the value you have entered ("/backoffice/tags") is NAME of the controller not the path under which it is available.

Add @RequestMapping("/backoffice/tags") on the controller's class and remove value from the @RestController annotation.

EDIT: Fully working example as per comment that it does not work - try to use this code please - and run locally from IDE.

build.gradle

buildscript {
    ext {
        springBootVersion = '1.2.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") 
        classpath("io.spring.gradle:dependency-management-plugin:0.5.2.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot' 
apply plugin: 'io.spring.dependency-management' 

jar {
    baseName = 'demo'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile("org.springframework.boot:spring-boot-starter-test") 
}


eclipse {
    classpath {
         containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
         containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

Tag.java

package demo;

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;

public class Tag {

    private final String tagName;

    @JsonCreator
    public Tag(@JsonProperty("tagName") String tagName) {
        this.tagName = tagName;
    }

    public String getTagName() {
        return tagName;
    }

    @Override
    public String toString() {
        final StringBuilder sb = new StringBuilder("Tag{");
        sb.append("tagName='").append(tagName).append('\'');
        sb.append('}');
        return sb.toString();
    }
}

SampleController.java

package demo;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/backoffice/tags")
public class SampleController {

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public void add(@RequestBody List<Tag> tags) {
        System.out.println(tags);
    }
}

DemoApplication.java

package demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

Answer 2

Actually When method name is available but method type is different than required type so this exception will throw 405.

Answer 3

I faced the same kind of error when I was developing. Please check the URL path is correctly mapped with the same as you are checking. Hope it resolves the problem.
