I am trying to write annotated class to fixedlength file with beanio. All classes are already annotated but I am getting exception
"Invalid field 'employees', in record 'team', in stream 'Tm': Type handler not found for type 'com.mycompany.bio.Employee'"
Below is my source code
public static void main(String[] args) {
StreamFactory factory = StreamFactory.newInstance();
StreamBuilder builder = new StreamBuilder("Tm")
.format("fixedlength")
.parser(new FixedLengthParserBuilder())
.addRecord(com.mycompany.bio.Team.class);
factory.define(builder);
Employee e1 = new Employee("EmpF1", "EmpL1", "Developer", "1", new Date());
Employee e2 = new Employee("EmpF2", "EmpL2", "Developer", "2", new Date());
Team team = new Team();
team.setTeamName("Great Team");
team.getEmployees().add(e1);
team.getEmployees().add(e2);
BeanWriter out = factory.createWriter("Tm", new File("C:\\Users\\user\\Desktop\\tm.dat"));
out.write(team);
out.flush();
out.close();
}
Team Class:
@Record(minOccurs = 1)
public class Team {
// @Segment(collection = ArrayList.class, minOccurs = 0, maxOccurs = Integer.MAX_VALUE) segments return single line team::teamName and 2 emp records, I want to see 3 lines 1.teamname 2 & 3 emp info
@Field(ordinal = 1, length = 106)
private List<Employee> employees;
@Field(ordinal = 0, length = 10)
private String teamName;
.....
}
Employee Class:
@Record(minOccurs=1)
public class Employee {
@Field(ordinal = 1, length = 30)
private String firstName;
@Field(ordinal = 2, length = 30)
private String lastName;
@Field(ordinal = 3, length = 30)
private String title;
@Field(ordinal = 4, length = 8)
private String salary;
@Field(ordinal = 5, format="MMddyyyy", length = 8)
private Date hireDate;
...
}
Quick solution is:
public static void main(String[] args) throws IOException {
StreamFactory factory = StreamFactory.newInstance();
StreamBuilder builderCSV = new StreamBuilder("Tm")
.format("fixedlength")
.parser(new FixedLengthParserBuilder())
.addRecord(com.mycompany.bio.Team.class)
.addRecord(com.mycompany.bio.Employee.class);
factory.define(builderCSV);
BeanWriter out = factory.createWriter("Tm", new File("C:\\Users\\topSecretUsername\\Desktop\\tm.txt"));
Employee e1 = new Employee("EmpF1", "EmpL1", "Developer", "1", new Date());
Employee e2 = new Employee("EmpF2", "EmpL2", "Developer", "2", new Date());
Team team = new Team();
team.setTeamName("Great Team");
team.getEmployees().add(e1);
team.getEmployees().add(e2);
out.write(team);
for (Employee e : team.getEmployees()) {
out.write(e);
}
out.flush();
out.close();
}
Team class:
@Record
public class Team {
@Field(ordinal = 1, length = 10)
private String teamName;
private List<Employee> employees = new ArrayList<>();
....}
Employee:
@Record
public class Employee {
@Field(ordinal = 1, length = 30)
private String firstName;
@Field(ordinal = 2, length = 30)
private String lastName;
@Field(ordinal = 3, length = 30)
private String title;
@Field(ordinal = 4, length = 8)
private String salary;
@Field(ordinal = 5, format="MMddyyyy", length = 8)
private Date hireDate;
....}
Output file content:
Great Team
EmpF1 EmpL1 Developer 1 20150622
EmpF2 EmpL2 Developer 2 20150622
