java - There was an unexpected error (type=Not Acceptable, status=406) for Spring @RestController, spring-boot -

i'm trying return xml @restcontroller method -

@restcontroller public class mcscontroller { . . @requestmapping(value = "/encoders", method = { requestmethod.get }, produces = { mediatype.application_json,         mediatype.application_xml }) public list<encodervo> getencoders() {      list<encodervo> encoders = null;     try {         encoders = infoservice.listencoders();     } catch (mcsexception e) {         logger.error("error in listing encoders : " + e.getmessage());     }     return encoders; } 

here encodervo.java -

@xmlrootelement public class encodervo {  @xmlelement private long id;  @xmlelement private string name;  @xmlelement private boolean flagactive;  public encodervo() { }  public encodervo(long id, string name, boolean flagactive) {     super();     this.id = id;     this.name = name;     this.flagactive = flagactive; }  public long getid() {     return id; }  public void setid(long id) {     this.id = id; }  public string getname() {     return name; }  public void setname(string name) {     this.name = name; }  public boolean getflagactive() {     return flagactive; }  public void setflagactive(boolean flagactive) {     this.flagactive = flagactive; }  }

when hit url /encoders in browser, below error -

there unexpected error (type=not acceptable, status=406). not find acceptable representation

the jackson related jars in calsspath -

• jackson-core-asl : 1.9.13
• jackson-jaxrs : 1.9.13
• jackson-mapper-asl : 1.9.13
• jackson-annotations : 2.6.3
• jackson-core : 2.6.3
• jackson-module-jaxb-annotations : 2.2.3
• jackson-jaxrs-json-provider : 2.2.3
• jackson-jaxrs-base : 2.5.4
• jackson-databind : 2.6.3

so, have mappingjackson2httpmessageconverter in classpath.

please suggest. in advance.

there solution work out-of-the-box, jax-rs bit worse output. solution uses jackson-dataformat-xml. add dependency project:

    <dependency>         <groupid>com.fasterxml.jackson.dataformat</groupid>         <artifactid>jackson-dataformat-xml</artifactid>     </dependency> 

response this:

<?xml version="1.0" encoding="utf-8"?> <list>    <item>       <id>1</id>       <name>testencoder1</name>       <flagactive>true</flagactive>    </item>    <item>       <id>2</id>       <name>testencoder2</name>       <flagactive>true</flagactive>    </item>    <item>       <id>3</id>       <name>testencoder3</name>       <flagactive>true</flagactive>    </item> </list> 

for further details please @ spring mvc way (jackson-dataformat-xml)
