I have a list/map of beans in EL, or at least I assume it is and I'm fed up with spending hours going through trying to work out which sections belong to each other. So I print it plain like ${example}
.
football.beans.FootballFixture@72bec69[match=f开发者_C百科ootball.domain.FootballMatch@773aa1d5[id=360496,competition=PREMIERSHIP,seasonId=2011,groupName=,roundType=,roundNumber=,matchPeriod=FULL_TIME,matchDay=3,venueId=33,venue=White Hart Lane,venueCity=London,homeTeamId=t6,awayTeamId=t43,homeScore=1,awayScore=5,scorers=[football.domain.Score@3d5bed54[567825,AWAY,2011-08-28 14:05:05.0,34,GOAL,Dzeko,,FIRST_HALF
Currently I am overriding toString()
on my beans every time. It'd be great to have something similar to PHP's print_r
in JSP. Anybody know how to stop my eternal headache caused by this problem.
Import the Jackson JSON library and do something like this (assuming "myList" is the list/map you already have defined):
ObjectMapper mapper = new ObjectMapper();
System.out.println( mapper.defaultPrettyPrintingWriter().writeValueAsString(myList) );
This would print out your complete list object as a string to standard out.
Hope this helps.
You can use Pojomatic lib.
If you use maven, add dependency to pom.xml
.
<dependency>
<groupId>org.pojomatic</groupId>
<artifactId>pojomatic</artifactId>
<version>1.0</version>
</dependency>
Then add @AutoProperty
annotation to class you want to read like PostVo.java
.
And, override toString method like this:
@Override
public String toString() {
return Pojomatic.toString (this);
}
You can override hashCode()
and equals(Object obj)
.
@Override
public boolean equals(Object obj) {
return Pojomatic.equals (this, obj);
}
@Override
public int hashCode() {
return Pojomatic.hashCode (this);
}
