到目前为止，我使用了Spring web MVC +数据JPA，我可以用H2编写集成测试 现在我正在使用Spring Boot，当我在集成测试中尝试使用H2时，我有一个奇怪的行为。我有以下2个实体（也使用lombok）：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Unemployment by Ward Bar Chart</title>
<style type="text/css">
.axis text{
font-family: Arial;
font-size: 13px;
color: #333333;
text-anchor: end;
}
path {
stroke: steelblue;
stroke-width: 2;
fill: none;
}
.axis path,
.axis line {
fill: none;
stroke: grey;
stroke-width: 1;
shape-rendering: crispEdges;
}
.textlabel{
font-family: Arial;
font-size:13px;
color: #333333;
text-anchor: middle;
}
}
</style>
<body>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
// Set the dimensions of the canvas / graph
var margin = {top: 20, right: 0, bottom: 60, left: 60},
width = 475;
height = 350;
padding = 100;
// Adds the svg canvas
var svg = d3.select("body")
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("viewBox", "0 0 " + width + " " + height);
// Parse the date / time
var parseDate = d3.time.format("%m/%d/%y").parse;
var formatTax = d3.format(",.2f");
// Set the ranges
var x = d3.time.scale()
.range([0, width - margin.right - margin.left], .1);
var y = d3.scale.linear()
.range([height - margin.top - margin.bottom, 0]);
// Define the axes
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom")
.ticks(5);
var yAxis = d3.svg.axis()
.scale(y)
.orient("left")
.tickFormat(function(d) {return "$" + d + "B"});
// Define the line
var valueline = d3.svg.line()
.x(function(d) { return x(d.Date); })
.y(function(d) { return y(d["Tax Collections"]); });
// Get the data
d3.csv("Yearly Tax Collections.csv", function(error, data) {
data.forEach(function(d) {
d.Date = parseDate(d.Date);
d["Tax Collections"] = formatTax(+d["Tax Collections"]/1000000000);
});
// Scale the range of the data
x.domain(d3.extent(data, function(d) { return d.Date; }));
y.domain([0, d3.max(data, function(d) { return d["Tax Collections"]; })]);
// Add the valueline path.
svg.append("path")
.attr("class", "line")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
.attr("d", valueline(data));
// Add the X Axis
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(" + margin.left + "," + (height - margin.bottom) + ")")
.call(xAxis);
// Add the Y Axis
svg.append("g")
.attr("class", "y axis")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
.call(yAxis);
// Y-axis labels
svg.append("text")
.attr("text-anchor", "middle")
.style("font-size", "13px")
.style("color", "#333333")
.attr("transform", "translate ("+ (padding/4) + "," +(height/2)+") rotate(-90)")
.text("Tax Revenue")
.style("font-family", "Arial");
// X-axis labels
svg.append("text")
.attr("text-anchor", "middle")
.style("font-size", "13px")
.style("color", "#333333")
.attr("transform", "translate("+ (width/2) + "," +(height-(padding/4)) + ")")
.text("Fiscal Year")
.style("font-family", "Arial");
//source
svg.append("text")
.attr("text-anchor", "middle")
.style("font-size", "13px")
.style("color", "#333333")
.attr("transform", "translate("+ (width/4.5) + "," +(height/1) + ")")
.text("Source: DC OCFO")
.style("font-family", "Arial")
//title for the chart
svg.append("text")
.attr("text-anchor", "middle")
.style("font-size", "16px")
.style("color", "#333333")
.attr("transform", "translate("+ (width/3) + "," +(height/30) + ")")
.text("DC Total Tax Revenues by Fiscal Year")
.style("font-family", "Arial");
svg.append("text")
.attr("text-anchor", "left")
.style("font-size", "10x")
.style("color", "#333333")
.attr("transform", "translate("+ (width/20) + "," +(height/12) + ")")
.text("2000 to 2015")
.style("font-family", "Arial")
//line labels
svg.append('g')
.classed('labels-group', true)
.selectAll('text')
.data(data)
.enter()
.append('text')
.filter(function(d, i) { return i === 0 || i === (data.length - 1) })
.classed('label',true)
.attr({
'x':function(d,i) {
return x(d.Date);
},
'y':function(d,i) {
return y(d["Tax Collections"]);
}
})
.text(function(d,i){
return "$" + d["Tax Collections"] + "B";
})
.attr("transform", "translate(" + margin.left + "," + margin.top + ")")
});
</script>
</body>
当我尝试将实体转换为DO时，我得到NullpointerException，因为只设置了Task的id，所有其他属性都为null。转换发生时我处于同一个事务中，因此应该加载属性。无论如何，我在调用转换器类之前尝试获取Task的'order'属性，但它是null。
@Entity
@Table(name = "EVENT_LIFE")
@Builder
@NoArgsConstructor
@AllArgsConstructor
@ToString
public class EventLifeEntity {
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "TASK_ID")
private TaskEntity taskEntity;
...
}
@Entity
@Table(name = "TASK")
@Builder
@ToString
@NoArgsConstructor
@AllArgsConstructor
public class TaskEntity {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
@Column(name = "ORDR")
private Integer order;
@Column(name = "COMMAND")
private String command;
...
}
Gradle依赖项：
@Service
public class RepositoryErrorSourceService implements ErrorSourceService {
....
@Override
@Transactional
public String search(Event event) {
...
EventLife eventLife = EventLife.builder()
.date(Calendar.getInstance())
.event(eventToDomainConverter.convert(eventEntity))
.task(command)
.eventStatus(EventStatusEnum.BEFORE_START)
.order(0).build();
EventLifeEntity eventLifeEntity = eventLifeEntityRepository.save( eventLifeToEntityConverter.convert(eventLife) );
LOGGER.debug("The following EvenEntity is saved: {}", eventLifeEntity);
// starting the first task of the workflow
command.execute( eventLifeToDomainConverter.convert( eventLifeEntity) );
...
}
}
所以我在集成测试中使用了很好的H2，但似乎我在春季启动时遗漏了一些东西。也有可能我忘记了某个地方的设置。无论哪种方式，我都被困住了 如果有人能帮助我那将是出色的！
谢谢，

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 忘了提，但我也试着用eager fetch类型。我甚至在调用转换器之前尝试引用特定属性但没有改变。
