Description

Class has 2 BigDecimal fields:

BigDecimal biddecimal123 = new BigDecimal("123");
BigDecimal biddecimal456 = new BigDecimal("456");

MultilineRecursiveToStringStyle produces this output:

BDToString@36baf30c[
biddecimal123=java.math.BigDecimal@7adf9f5f[
intVal=<null>,
scale=0
],
biddecimal456=java.math.BigDecimal@63961c42[
intVal=<null>,
scale=0
]
]

 

ToStringStyle.MULTI_LINE_STYLE doesn't have this problem. It was introduced with method

@Override
public void appendDetail(final StringBuffer buffer, final String fieldName, final Object value)

of MultilineRecursiveToStringStyle. It doesnt'n treat BigDecimal as a primitive type. So I had to do the following to solve my issue:

 

class FixedMultilineRecursiveToStringStyle extends MultilineRecursiveToStringStyle{
    @Override
    public void appendDetail(StringBuffer buffer, String fieldName, Object value) {
        if (!BigDecimal.class.equals(value.getClass())){
            super.appendDetail(buffer, fieldName, value);
        } else {
            buffer.append(value);
        }
    }
}
