Spring Boot: Configuring AuthenticationManager with custom UserDetailsService

In my Spring Boot application, I am using JWT and a custom UserDetailsService. My AuthenticationManager is configured in a class annotated with #Configuration using the following method:
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth, DataSource dataSource) throws Exception {
auth
.userDetailsService(userDetailsService)
.and()
.jdbcAuthentication()
.dataSource(dataSource)
.passwordEncoder(passwordEncoder());
}
Even though I specified a UserDetailsService, I am faced with the following problem: When my JWTLoginFilter intercepts the login request, and getAuthenticationManager().authenticate(token)
is called, I get the following exception:
org.springframework.security.authentication.InternalAuthenticationServiceException: PreparedStatementCallback; bad SQL grammar [select username,password,enabled from users where username = ?]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'butler-test.users' doesn't exist

Setting a query using usersByUsernameQuery(query) on my AuthenticationManagerBuilder solves this problem, but is this the only solution? Shouldn't the UserDetailsService provide the information needed to retrieve the UserDetails for a username?
In case it helps, here is a snippet from the JWTLoginFilter:
#Override
public Authentication attemptAuthentication(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws AuthenticationException, IOException, ServletException {
AccountCredentials credentials = new ObjectMapper().readValue(httpServletRequest.getInputStream(), AccountCredentials.class);
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(credentials.getUsername(), credentials.getPassword());
return getAuthenticationManager().authenticate(token);
}
This is my user entity (there are subclasses for specific users):

Your configuration is wrong. You defined 2 authentication mechanisms, one is a user details service, and the second is a JDBC authentication.
In order to authenticate a user you only need one kind of mechanism to do that.
Your JVM "complains" about a bad SQL grammar, and if you'll examine the exception more closely you'll see that in particular JVM "complains" that he can't find the users table in your DB.
It seems that your JDBC authentication kicks in and tries to find the user credentials in the users DB table.
When you use this kind of authentication (JDBC) that is where and how Spring will try to authenticate the users, by trying to find a matching record within the users table in your DB.
You obviously mixing 2 authentications mechanisms by trying to read from:
#Table(name = "u_userdetails")
If you want to use JDBC authentication make sure to read the credentials from users table.
And not from:
#Table(name = "u_userdetails")

a hibernate LazyInitializationException which is very trick

I have two piece of code segments, they are almost exactly the same, except their locations are different, one locates in RestLoginDLCtrl(a controller) the other locates in CouponManagerController(a controller).But one code segment is right, the other one throws org.hibernate.LazyInitializationException.
I know how to solve my problem. confused me the most is why one is OK the other is wrong, but they are almost the same code. why? Any help would be appreciate.
ConversionCode is a value object which has a set named codeRewards and managerService is a service class.
note:
Finally, I found some interesting phenomena. when I use ajax way to post the http request, two methods both well:
$.ajax({
type: "POST",
url: "/CouponInfo/useConversionCode.do",
data: {
code: key
},
dataType: "json",
success: function (data) {
}
});
But when I use form way, two methods both did not work:Does hibernate lazy initialize mechnism has relationship with http request way?
<form action=""></form>

failed to lazily initialize a collection of role: com.yiqixiangqian.entity.ConversionCode.codeRewards, no session or session was closed
The useConversionCode() method which locates in CouponManagerController controller is OK:
The useConversionCode() method which locates in RestLoginDLCtrl controller is wrong and throws a LazyInitializationException exception:

Finally, I found some interesting phenomena. when I use ajax way to post the http request, two methods both well:
$.ajax({
type: "POST",
url: "/CouponInfo/useConversionCode.do",
data: {
code: key
},
dataType: "json",
success: function (data) {
}
});
but when I use form way, two methods both did not work:
<form action=""></form>
Does hibernate lazy initialize mechnism has relationship with http request way?

I know how this issue occured.Suddenly, I found there is a OpenSessionInViewFilter in the web.xml file.
<filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
In my form post request way, I did not add the .do request suffix, so the OpenSessionInViewFilter did not work, so the LazyInitializationException occured.
But the ajax post request way added the .do request suffix, so the OpenSessionInViewFilter worked and LazyInitializationException did not occur.

How to display a List with Spring <form:input>

I'm trying to show a list of object 'Persona' using <form:input>.
This is my form
<form:form modelAttribute="persona">
<c:forEach items="${personaList}" varStatus="contatore" var="persona">
<form:input path="persona[${contatore.index}].id"/><br/>
...
</c:forEach>
</form:form>
This is the error I get:

Thank you

Use ${persona.id} instead of persona[${contatore.index}].id
This line:
<c:forEach items="${personaList}" varStatus="contatore" var="persona">
means "repeat the content for each item in personaList, while tracking the iteration status in contatore and assigning the current item into persona". So the framework has already done the assignment persona = personaList[contatore.id] for you.
Also, the whole expression to be evaluated needs to be inside the ${...} markup.

Use this :
<form:form modelAttribute="persona">
<c:forEach items="${personaList}" varStatus="count" var="person">
<input type="text" name="persona.persona[${count.index}].id" value="${person.id}"/><br/>
</c:forEach>
</form:form>

java jpa ManyToOne cascade remove not working as expected

I have two tables and on one of which I want to perform cascade on delete operation. I have tried using annotations both on the variable and on the getter method as well, but the variable one gives me this error:

Which is out of question because the column its referring to has BIGINT(10) size.
And, when I try using many to one annotation on getter method its not doing anything at all.

And here is my child class where I have used many to one annotation:
import org.hibernate.annotations.*;

import javax.persistence.Entity;
import javax.persistence.Table;
#Entity
#Table(name="ac_ua_ip")
public class IPUser extends BaseEntity{

public IPUser (String ip, String comment, UserAccount userAccount){

this.comment = comment;
this.setUserAccount(userAccount);
}
#Column (nullable = false)

}
#Column
public String getComment() {
return comment;
}
public void setComment(String comment) {

}
#ManyToOne(cascade = CascadeType.REMOVE)
public UserAccount getUserAccount() {
return userAccount;
}
public void setUserAccount(UserAccount userAccount) {
this.userAccount = userAccount;
}
}
And, I have removed lot of methods from parent class here just to have a clarity.
Any suggestions as to what I am doing wrong?

You will have to manage that problem manually, as it really does NOT make sense to cascade the remove operations from a ManyToOne relationship (otherwise your DB will not be consistent, as there could remain some IPUser entities without UserAccount).
See this answer for an excerpt from the JPA specification + a similar problem.

Alright, here's how I made it work.
I hope it goes all ok with the etiquette of answering self-asked-questions.
I added a reference to IPUser class in UserAccount class and it worked smoothly now. Here is the snippet I added:
private List<IPUser> ipUserList;
#OneToMany(mappedBy = "userAccount", fetch = FetchType.LAZY)
#Cascade({CascadeType.DELETE})
public List<IPUser> getIpUserList() {
return ipUserList;
}
public void setIpUserList(List<IPUser> ipUserList) {
this.ipUserList = ipUserList;
}
Please feel free to update my answer or ask any question regarding this.
