Getter not found (class: %s, property: %s)

Error message

Getter not found (class: %s, property: %s)

What it means

BeanUtils.getGetter() resolves a JavaBean getter method for a property by walking the class hierarchy via findGetter(). If no getter exists for the given property name, it throws a RuntimeException naming the class and property. This is a programming/reflection error — code referenced a bean property that does not exist.

Solutions

1. Check the exact property name and its capitalization against the bean class; add or fix the getter (getX()/isX())
2. Update all string references after refactoring — search the codebase for the old property name
3. Compile-time safety: prefer method references/constant property names over raw strings where possible
4. At runtime, validate property existence reflectively before use and fail fast with a clear message

Example fix

// before
Method m = BeanUtils.getGetter(PullRequest.class, "tilte"); // typo
// after
Method m = BeanUtils.getGetter(PullRequest.class, "title"); // matches getTitle()

public static boolean hasGetter(Class<?> clazz, String prop) {
    String cap = Character.toUpperCase(prop.charAt(0)) + prop.substring(1);
    try {
        clazz.getMethod("get" + cap);
        return true;
    } catch (NoSuchMethodException e) {
        try { clazz.getMethod("is" + cap); return true; }
        catch (NoSuchMethodException e2) { return false; }
    }
}

if (hasGetter(PullRequest.class, "title")) {
    Method m = BeanUtils.getGetter(PullRequest.class, "title");
}

try {
    Method m = BeanUtils.getGetter(clazz, property);
} catch (RuntimeException e) {
    if (e.getMessage().startsWith("Getter not found"))
        throw new ConfigurationException("Check property name against " + clazz.getName(), e);
    throw e;
}

When it happens

Trigger: Calling BeanUtils.getGetter(clazz, propertyName) where the class (and its superclasses) define no method matching the JavaBean getter convention for that property (missing getX()/isX(), wrong case, or property renamed).

Common situations: Renaming a bean field without updating string-based property references (query criteria, Wicket property models, YAML/setting keys); typos in property names; passing an interface/class different from the actual bean type.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
