Closed 7 years ago.
I'm having a hard time fixing this 406 error with spring MVC. What I want to do is to make an Ajax call and get a json response. Also I'm trying to output that json using alert(js). This is how I implement it.
My Controller:
#RequestMapping(value="/search", headers="Accept=*/*", produces=MediaType.APPLICATION_JSON_VALUE) // no 'params' argument
#ResponseBody
public Customer findByFirstName() {
Customer test = new Customer();
test.setFirstName("test");
return test;
}
Customer:
#Entity
#Table(name="customer",catalog="revised_cws_db")
public class Customer implements java.io.Serializable {
#Id #GeneratedValue(strategy=IDENTITY)
#Column(name="id", unique=true, nullable=false)
private int id;
#Version #Temporal(TemporalType.TIMESTAMP)
#Column(name="timestamp", nullable=false)
private Date timestamp;
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="address_id", nullable=false)
private Address address;
#Temporal(TemporalType.DATE)
#Column(name="birth_date", nullable=false, length=10)
private Date birthDate;
#Column(name="first_name", nullable=false, length=45)
private String firstName;
#Column(name="middle_name", nullable=false, length=45)
private String middleName;
#Column(name="gender", nullable=false, length=45)
private String gender;
#Column(name="contact_number", length=45)
private String contactNumber;
#Column(name="family_members_count", nullable=false, length=45)
private String familyMembersCount;
#Column(name="occupation_id", nullable=false)
private int occupationId;
#Column(name="active", nullable=false)
private boolean active;
#OneToMany(fetch=FetchType.LAZY, mappedBy="customer")
private Set<Issues> issueses = new HashSet<Issues>(0);
#OneToMany(fetch=FetchType.LAZY, mappedBy="customer")
private Set<Account> accounts = new HashSet<Account>(0);
public Customer() {
}
public Customer(int id, Address address, Date birthDate, String firstName, String middleName, String gender, String familyMembersCount, int occupationId, boolean active) {
this.id = id;
this.address = address;
this.birthDate = birthDate;
this.firstName = firstName;
this.middleName = middleName;
this.gender = gender;
this.familyMembersCount = familyMembersCount;
this.occupationId = occupationId;
this.active = active;
}
public Customer(int id, Address address, Date birthDate, String firstName, String middleName, String gender, String contactNumber, String familyMembersCount, int occupationId, boolean active, Set<Issues> issueses, Set<Account> accounts) {
this.id = id;
this.address = address;
this.birthDate = birthDate;
this.firstName = firstName;
this.middleName = middleName;
this.gender = gender;
this.contactNumber = contactNumber;
this.familyMembersCount = familyMembersCount;
this.occupationId = occupationId;
this.active = active;
this.issueses = issueses;
this.accounts = accounts;
}

jackson-mapper-asl 1.9.13
jackson-core 2.4.4
